The 7 Essential Stops in San Ysidro, Otay Mesa & Otay Mesa-Nestor, Ranked

In 2006, brothers Jorge and Miguel borrowed a friend's food truck, parked it in a lot on Flower Avenue in Nestor, and started selling birria from what San Diego Magazine described in 2020 as a "mom-tested recipe." It caught on. They moved into the building, then took over the space next door, then the floor upstairs, and brought in a third brother, Carlos, as chef. The sign out front says Ed Fernandez Restaurant Birrieria. Most people just call it Fernandez.

It's the first stop on this list because nothing else in San Ysidro, Otay Mesa or Otay Mesa-Nestor gives you a better reason to set an alarm. The birria is beef, slow-cooked into a stew with a mix of chiles and spices (cloves, cinnamon, garlic and cumin among them), and the restaurant describes it as bold without being spicy. It comes as tacos with cilantro and diced onion, or as an orden: a steaming bowl with warm tortillas on the side, so you can build your own tacos or eat it straight from the bowl. Radishes, limes and a house red salsa are there for both.

The order is the quesabirria with a cup of consommé for dipping. That deeply flavored broth gets a lot of the love, and so do the portions and a morning line that keeps moving. After that, the signature tacos are where the fun is. The Quesotaco con Nervio adds tendon. The Quesotaco extremo starts with a house-fried tortilla stained red by the consommé, then piles on melted cheese and birria beef crisped on the griddle. There's a Chupacabras, too, and a quesotaco made with no tortilla at all. Feeding a bigger table? Add a torta. The shop still proudly points to a 2022 Yelp honor for the best birria taco.

Timing is everything here. Fernandez opens at 6 AM Wednesday through Sunday, closes at 2 PM, and stays dark Monday and Tuesday. Lines build as the morning goes on and the lot is tight, so the first half of the morning is your best window. Park legally and keep the neighboring businesses' entrances clear. On a Wednesday, Saturday or Sunday, the South Bay Drive-In swap meet is running a few blocks away on Coronado Avenue, and breakfast turns into a whole morning out.

Las Americas Premium Outlets is about as far south as San Diego shopping gets, sharing its corner of San Ysidro with the trolley's last stop and the port of entry. The San Diego Tourism Authority counts some 190 stores and calls it the region's largest outlet mall, with names like Nike, Coach, Levi's, H&M and Karl Lagerfeld Paris spread across an open-air complex in San Ysidro.

What earns it the No. 2 spot is how easily it folds into a day down here. The UC San Diego Blue Line ends at the San Ysidro Transit Center, which sits right next to the property, so a car is optional. Trolleys run from about 4:30 in the morning until 1 AM, the Route 910 bus covers the overnight gap, and the adult one-way fare was $2.50 at last check. That matters most on holiday weekends, when the roads around the border back up and the parking search gets long.

If Ed Fernandez is the reason to come south, Las Americas is the easy add-on. Shoppers point to the range of stores, the deals, the food on site and how walkable the whole place is. Bargain depth changes from store to store, so it pays to compare before you buy.

The complex covers a lot of ground, and wandering can eat the whole afternoon. The smart move is a short list of stores, made before you leave home, that keeps the visit focused. On hot days the open-air walkways between buildings warm up, so hit your big stops early. Driving in? Follow the signs carefully near the port of entry, and never improvise a U-turn by the border lanes.

The South Bay Drive-In has been showing movies in Otay Mesa-Nestor since 1958, and it's the stop on this list that turns an ordinary weekend night into a plan. It opened with a single 100-foot screen. A 1974 remodel replaced that screen and added two more, giving it the three it runs today, and a 2008 upgrade brought new projectors and FM stereo transmitters before the switch to a fully digital system in 2013. The whole place leans into a nautical theme, complete with an "Ahoy, Matey!" and the line "where cinema meets the sea."

These days, movies run Friday, Saturday and Sunday nights, and the coming weekend's showtimes go up on Wednesday. One ticket covers both films on your screen when it's a double feature, and at last check admission was $10 for adults and $1 for kids 5 to 9, paid at the gate by card. The box office opens an hour before the first show, and that's when the theater suggests you arrive. Showtimes run earlier in winter and later in summer, and the show goes on rain or shine.

Sound comes through your car's FM radio. To spare your battery, bring a battery-powered portable FM radio, because phone radio apps won't pick up the signal. Spanish audio for most movies is available through the Theater Ears app. The snack bar does popcorn, candy and carne asada nachos, cash only, and you're welcome to bring your own food and non-alcoholic drinks. Chairs are fine inside your own space, truck beds work too, and big SUVs park toward the back.

Fans love the nostalgia, the value, the double features and the date-night feel, and they mention staff pitching in when a battery dies. Summer entrance lines can stretch back onto Coronado Avenue, so early really is better, and restrooms can close before the second feature ends. On Wednesday, Saturday and Sunday mornings, the same address hosts a swap meet from 6 AM to 2 PM.

When the night runs long in Otay Mesa-Nestor, the Palm Avenue Tacos El Gordo is the answer. It's open until 1 AM Sunday through Thursday and 2 AM on Friday and Saturday, and it serves the kind of taco the company has been making since it was founded in Tijuana in 1972. The family-owned business opened its first U.S. shop in San Diego in 1998, reached Las Vegas in 2010, and Palm Avenue is one of its three California locations, along with Downtown San Diego and Broadway in Chula Vista.

The tortillas are handmade corn, and the salsas and guacamole are made from scratch every day. Start with adobada, the spiced pork that the praise for this shop keeps circling back to. When two tacos won't cut it, order a mula: your choice of meat with cheese and toppings on a double corn tortilla. The menu keeps going from there. Suadero is brisket, the azteca pairs grilled beef with cactus, and cabeza, lengua, tripa and buche are there for the curious. Sopes come on a thick handmade tortilla, and fries piled with meat make a good table snack.

Here's how the counter works. Lines are split by meat, so read the signs before you settle in, and join the adobada line specifically for the adobada. With friends, send one person to each line and meet up at the end. Once your order is in, things move quickly.

If Ed Fernandez owns the morning, El Gordo covers the other end of the clock. Service in the final hour can be uneven, so aim to arrive before the last stretch of the night.

Beyer Deli sits in Suite A105 of a small office park on Beyer Boulevard in Otay Mesa-Nestor, a quarter mile off the 905, and it has a following most restaurants would envy. The family-owned shop has made Yelp's annual Top 100 restaurants list, landing at No. 4 in 2023 and No. 14 in 2025. The reason is simple: big, carefully made sandwiches, served the same way for a very long time.

Owners Michael and Dina run the counter themselves with a couple of employees, and as the San Diego Reader put it in 2025, they've done it in much the same way for more than 25 years. The bread comes from a local bakery. Specialty sandwiches go on torta rolls, also called telera, while the triple-decker clubs come on toasted sourdough or squaw bread and the Italian-style subs on chewy rolls. The meats are hand-picked and generous, with plenty of shredded lettuce, and sandwiches come with pickle spears.

The order regulars keep returning to is the New Yorker on torta bread. For something with a little South Bay in it, the South of the Border stacks roast beef, melted provolone, mayo and roasted Ortega chiles on a torta roll. Portions run large, and fans also bring up the friendly service and a sandwich that comes out the same every time.

This one takes a little planning. It's cash only, open Tuesday through Friday from 9 AM to 3 PM, and seating is limited. Save the suite number before you drive over, since the storefront is easy to pass. The Otay Valley Regional Park ranger station is on Beyer Boulevard too, so a sandwich to go and a walk in the river valley make a very good weekday.

Otay Valley Regional Park is the South Bay's big stretch of open space, and the simplest way in is the ranger station at 2155 Beyer Boulevard in Otay Mesa-Nestor. From there, 8.3 miles of non-motorized, multi-use trail follow the Otay River Valley between the San Diego National Wildlife Refuge and I-805. The system also takes in seven ponds and seven staging areas, and the birds are a big part of what people love here.

The park is a team project. The County of San Diego and the cities of San Diego and Chula Vista agreed in 1990 to plan it together, and the long-range vision runs about 11 miles inland, from the salt ponds at the mouth of the Otay River to Lower and Upper Otay Lakes. The County calls it one of the major open space areas within southern San Diego County, and hiking, biking and horse trails are all part of the plan. Visitors praise the trails, the cycling and a side of the South Bay that feels open and far less developed than the roads around it.

The ranger station makes the easiest start. The park is open sunrise to sunset, but public vehicle access and restrooms run only from 8 AM to 5 PM, so plan your parking around the shorter window. Long stretches of trail have little shade, which makes an out-and-back the smart shape: start early, carry plenty of water and turn around when the heat says so. Conditions can vary between the parts each agency manages, and off-road vehicles are prohibited by law.

Cross Border Xpress is the most useful building in Otay Mesa if you're flying out of Tijuana, and it's the one stop on this list that comes with rules. The terminal on Otay Pacific Drive connects to Tijuana International Airport by an enclosed bridge, so passengers walk from the U.S. side directly into the airport. It runs 24 hours a day, 365 days a year, and it's open only to ticketed airline passengers.

Here's how eligibility works. Heading south, you need a CBX ticket plus a boarding pass for a flight leaving Tijuana within 24 hours. Coming north, you need a boarding pass showing you landed within the last two hours, and you have to go straight from the secure baggage-claim area to the bridge. Step outside that area and the bridge is no longer an option. For a trip into Tijuana without a flight, the San Ysidro crossing is the way to go.

The time it saves is the big draw, along with the convenience of the terminal and how neatly it fits a Tijuana itinerary. The friction points are well known, so you can plan around them. Buy the CBX ticket and reserve parking before you leave home, since overflow parking is unpaved and the counters back up when several flights land at once. Double-check your documents before the trip, too, because they're a common snag.
