The bright, citrus-cured cousin of ceviche — what's in it, how spicy it gets, and how to order your first one.

Our doors, at golden hour
The Garcia family · our owners
Cured & plated to orderCosta Brava began with a simple idea: bring the bright, citrus-forward mariscos of the Sinaloa coast to the heart of South Texas — and let the border add its own smoke and heat.
Every morning we break down the day's catch, press fresh limes by the case, and roast salsas from scratch. Nothing is cured until you order it, so each aguachile hits the table snapping-fresh.
It's coastal food with border soul — meant to be shared loudly, over a cold michelada, with people you love.

From the Garcia family who started it all, to the chefs breaking down the morning's catch, to the servers who know the menu by heart — this is the team that makes every visit feel like the coast.
Familiar faces, warm welcomes, and a kitchen that treats your table like family.
Birthdays, rehearsal dinners, office parties, quinceañeras — we host it all, or bring the coast to you anywhere in San Antonio.
A staffed raw bar of oysters, aguachiles and ceviche, shucked and cured to order for your guests.
Build-your-own taco bars and bubbling molcajetes, sized for groups of 10 to 100.
A semi-private coastal room that seats up to 40, with its own bar and playlist.
We bring the coast to your office, home or venue — setup, service and cleanup included.
Tell us your date, headcount and vibe. We'll build a coastal spread your guests won't stop talking about — from raw bars to whole grilled snapper.
Request a catering quoteHand-painted talavera, a driftwood raw bar, string lights over the patio, and a wave mural that greets every guest at the door.
