Best Seafood in Downtown Houston: Gulf Oysters, Crawfish, Redfish

For seafood in downtown Houston, go to Guard and Grace for Gulf oysters and seafood towers, La Fisheria on Market Square for Galveston Bay oysters and ceviche, and Zydeco Louisiana Diner for weekday crawfish étouffée. Round out the list with the Downtown Aquarium Restaurant, McCormick & Schmick’s, Vic & Anthony’s, Hearsay Market Square and Pappadeaux inside the George R. Brown Convention Center. All eight are inside downtown Houston and were confirmed open on their own websites in October 2026.

Here’s the line to remember: downtown’s best crawfish isn’t a boil. It’s a plate of étouffée at a Cajun diner that has been feeding downtown office workers since 1988, made from family recipes that trace back to Acadia Parish, Louisiana.

Where does downtown Houston start and end?

For this guide, downtown Houston is everything inside the freeway ring formed by I-45 on the west and south (the Pierce Elevated), I-69/US-59 on the east and I-10 on the north. That takes in the Main Street corridor, Market Square and the Historic District, the Theater District, the George R. Brown Convention Center and Avenida Houston, and the blocks around Daikin Park. EaDo, east of US-59, and Midtown, south of the Pierce Elevated, have their own guides. New to the area? Start with our downtown Houston neighborhood page.

How we chose

We picked restaurants inside our downtown boundary where seafood is a real reason to go, not a single shrimp dish on a long menu. Each one had to show a current address, hours or live reservations on its own official website in October 2026, and we read every menu we could open ourselves to pick the dishes below.

We left out places we couldn’t confirm on an official site. Hours, prices and menus change, and Gulf catches depend on the season, so treat everything here as typical and check the restaurant’s site before you go. If you want a full crawfish boil, downtown doesn’t really do one; our Houston crawfish guide has the boil houses.

Oysters and raw bars

Guard and Grace

One Allen Center, 500 Dallas St · steakhouse with a seafood bar · lunch weekdays, dinner Monday to Saturday

Guard and Grace in downtown Houston is a steakhouse, but its seafood bar is one of the most serious in the neighborhood. Oysters come raw or grilled, from the Gulf and the East Coast, by the half dozen or dozen. The two seafood towers are named the Boss and the Chairman; the bigger one stacks a dozen shrimp, a dozen oysters, a whole lobster, crab fingers and sashimi.

What to order: the Grilled TX Redfish on the Half Shell with Gulf crab fried rice at dinner, or the andouille and seafood gumbo with Gulf shrimp, crab and Texas redfish at lunch.

Insider tip: weekday happy hour (typically 3 to 6 p.m.) includes oysters on the half shell, which is the cheapest way into the room. The restaurant describes itself as Michelin-recommended, and the dress code is casual elegant.

Best for: a business dinner or a towering celebration. More raw-bar picks in our seafood towers guide.

La Fisheria

Market Square, 213 Milam St · Mexican coastal seafood · open daily

La Fisheria on Market Square in downtown Houston cooks the seafood of Mexico’s coasts, and its menu names Galveston Bay as the source of the oysters in its Ostiones Oro Negro. Order those, or the Ostiones a la Parrilla grilled oysters, then a Trio de Ceviches to share.

What to order: Vuelve a la Vida, the Mexican seafood soup; Huachinango a la Veracruzana, grilled red snapper in a tomato, olive and güero pepper sauce; or, for a group, the whole catch of the day, sold by weight.

Insider tip: weekday happy hour typically runs 3 to 6 p.m., and weekday lunch (11 a.m. to 3 p.m.) brings fish, shrimp, octopus and lobster tacos. It sits across from Market Square Park.

Best for: a long Market Square lunch or after-work oysters. See more in our Houston oysters guide.

McCormick & Schmick’s

GreenStreet, 1201 Fannin St · seafood and oyster bar · open daily

McCormick & Schmick’s downtown Houston location sits near Discovery Green and runs an ice bar of oysters on the half shell. Be clear on what you’re getting: the oysters listed on its menu are East Coast oysters from Massachusetts, not Gulf oysters. The Gulf comes in elsewhere, with Palacios Texas redfish blackened and topped with lump crab.

What to order: the redfish, the seafood gumbo with lump crab and shrimp, or the chilled seafood tower for four to six.

Insider tip: the restaurant’s Buck Shuck Fridays put oysters at $2 during happy hour, and weekday happy hour typically runs 3:30 to 7 p.m.

Best for: oysters before a show or a game, without a reservation scramble.

Crawfish, gumbo and Gulf Coast plates

Zydeco Louisiana Diner

South end of downtown, 1119 Pease St · Cajun · lunch weekdays, dinner Thursday to Saturday

Zydeco Louisiana Diner has served South Louisiana home cooking in downtown Houston since 1988, using recipes the restaurant says were handed down by Mama Lou from Acadia Parish. It’s a lunch place first: typically 11 a.m. to 2 p.m. on weekdays, with dinner Thursday through Saturday evenings.

What to order: crawfish étouffée, which runs as the daily special on Mondays, Wednesdays and Fridays and on the dinner menu. Any day, get the crawfish po’boy or crawfish platter, a cup of seafood gumbo, or the Thursday seafood courtbouillon.

Insider tip: plan around the calendar. If étouffée is the goal, Monday, Wednesday or Friday lunch is your window.

Best for: a fast, filling workday lunch.

Hearsay Market Square

Market Square, 218 Travis St · gastropub · open daily

Hearsay Market Square sits in the W.L. Foley Building, built in 1889, with an iron and brass staircase added when the building was redesigned in 1994. The menu says it serves fresh Gulf seafood, and that shows up in three dishes worth ordering.

What to order: the Crab-Crusted Redfish, a Gulf redfish topped with crab; the Gulf Coast gumbo with shrimp, crab, chicken and sausage; or the blackened redfish tacos at lunch.

Insider tip: weekend brunch runs from 10 a.m. to 3 p.m., and weekday happy hour from 3 to 6 p.m. It has no raw oysters, so do oysters at La Fisheria across the square first.

Best for: a group that wants seafood and a cocktail list in a historic room.

Pappadeaux Seafood Kitchen (Downtown)

George R. Brown Convention Center, 1001 Avenida de las Americas · seafood · open daily

The downtown Pappadeaux Seafood Kitchen is built into the George R. Brown Convention Center, and the company calls it Pappadeaux No. 41. It typically opens at 11 a.m. daily, takes reservations and does to-go orders, which makes it the easiest sit-down seafood meal during a convention or a Rockets game at Toyota Center.

What to order: check the downtown location’s online menu before you go, especially in spring if you’re hoping for crawfish.

Insider tip: it is closed on Thanksgiving Day. Planning around a show? Our George R. Brown Convention Center guide covers entrances and parking.

Best for: conventioneers and families on Avenida Houston.

Special nights out

Downtown Aquarium Restaurant

Downtown Aquarium, 410 Bagby St · seafood · open daily

The Downtown Aquarium Restaurant seats you around a floor-to-ceiling, 150,000-gallon aquarium, inside a complex built from two downtown landmarks: Fire Station No. 1 and the Central Waterworks Building.

What to order: oysters on the half shell, sautéed redfish with lump crabmeat, or the Louisiana Cajun pasta with crawfish tails. The fried seafood platter includes cornmeal-crusted Gulf oysters.

Insider tip: restaurant hours differ from the exhibit and ride hours, so check before you go. Pair dinner with the exhibits using our Downtown Aquarium guide.

Best for: kids, visitors, and anyone who wants their dinner to come with a view of the fish.

Vic & Anthony’s Steakhouse

Ballpark blocks, 1510 Texas Ave · steakhouse · dinner nightly, lunch Fridays

Vic & Anthony’s in downtown Houston was founded by Tilman Fertitta and his father, Vic, and the restaurant says it is the only Landry’s concept built from the ground up. Steak is the headline, but the seafood is done with care.

What to order: the Gulf red snapper with jumbo lump crab and sherried lobster sauce, the jumbo lump crab cake, or the seafood tower.

Insider tip: the bar typically opens at 4 p.m. daily, and the lounge has live music most nights. The dress code is strict, so skip the jersey. Heading to a game? See our Daikin Park guide.

Best for: a big-occasion dinner before or after an Astros game.

Save this: a downtown seafood day

• Weekday lunch (Monday, Wednesday or Friday): crawfish étouffée and a cup of seafood gumbo at Zydeco Louisiana Diner.
