The main dining room was noisy and loud. There was a band practicing at 2:30 pmband was way too loud for the small dining room, and I had a hard time holding a conversation. Food was great and the service was very good.

Great food. I ordered octopus well, cooked soft and juicy, generous portions,
Service needs more experience. There was a 10 people table, and everything looked like slowed. The bar we order beer it came late and the menu prices are diferent than what you're charged no big deal Seafood fluctuate in price but a photocopy off your new prices helps until you get new menus.
The atmosphere is ok, but tvs with a frozen channel is no to appealing

The food was alright. I grew up eating cóctel de camarones con salsa tapatío, ketchup, cilantro, y (mucho) limón, and obviously some water. For anyone who enjoys their shrimp cocktail the way that we did, these guys use Clamato. It wasn’t bad but it wasn’t ‘authentic’ to me. I hope this helps! My husband had chipotle shrimp and it was good, but not as spicy as my mom’s too. Their food is pretty alright!
