Lionfish
Our pickLionfish is the Gaslamp Quarter dinner worth booking. It's a chef-driven coastal seafood and sushi restaurant at 435 Fifth Avenue, and it's our pick for the best restaurant in the Gaslamp Quarter because it gives the neighborhood what it needs most: a proper sit-down dinner where the cooking leads and the rest of the night follows.
Start at the raw bar. It comes up in review after review, along with the small plates, and it sets the tone for a menu built around seafood and sushi. The duck is the other headline. Recent reviews have zeroed in on the duck and the duck bao buns, so get at least one of them on the table between the oysters and the hand rolls. With this many small plates, a few orders passed around the table is the easy way to cover the menu.
If you can get there right at 5 on a weekday, do. Dinner starts at 5 PM, and on weekdays the first hour has its own menu: $1.50 oysters, $9 hand rolls, $10 cocktails, $9 wine by the glass and $7 beer. It's an easy way to taste across the menu before you settle into a full dinner. It also makes for a smooth handoff if you're turning the afternoon into a crawl, since La Puerta's happy hour on Fourth Avenue ends at 5, right when this one begins.
Of the six places on this list, Lionfish is the one built around a reservation and a long evening at the table. If La Puerta is the party and Tacos El Gordo is the after-party, Lionfish is the dinner you plan the day around. It's dinner only, with no lunch service, and it runs until 9 PM Sunday through Thursday and 10 PM on Friday and Saturday, so treat it as the early anchor of a Gaslamp night and save the tacos for later.
Two small things help. Book ahead if your group is big, and bring a layer if you're hoping for the patio. Provisional Kitchen, the morning pick at the end of this list, sits on the same block at 425 Fifth, so a whole Gaslamp day can start and finish within a few steps of each other.
