Went here for dinner, the staff are friendly and prompt. The menu also boasts of good number of options. We loves the coconut mojito, and the baja tacos. Although, the grilled salmon could have been a bit better, it felt a bit oily for our liking.

We went at night on a Friday night, the service was fast and staff was all nice. The waiter recommended some dishes for my friend and I we had the fried fish and the ceviche. It was really delicious. We also had mojitos de parcha which were really good! Definitely recommend 10/10 price was reasonable for quality of food.

San Juan, PR We didn’t need a reservation and were seated right away. This is seafood and meat. Very little for a vegetarian. But a few choices. I had the vegetable mofongo. A cheese empanada. A passion fruit mojito. Bottled water. My husband had oysters, which were from Boston. Go figure. Horseradish sauce served with it was bland. Blue Moon beer. If you know anything about the beer it’s served with an Orange. This was served with a bit of Orange juice in the glass. That’s a new one. Not fresh squeezed either. I also ordered truffle fries which were good. My husband had Mahi Mahi with capers and a lemon sauce. I’m not sure I’d come again. I’d rather try the other restaurants. Parking is valet or if you’d like to find street parking you can. The area looks a bit sketchy to some I would say. I’m not intimidated but I think some might be. Try it. If you love seafood or meat, you’ll love this More vegetarian options would be appreciated. Even the rice and beans had meat.

Came here after a recommendation from my hotel, and I’m so glad I did. I ordered one fish taco to try and the fried red snapper with tostones. The fish taco was honestly one of the best I’ve ever had — fresh, flavorful, and perfectly balanced. The snapper took a little while to arrive, but it was well worth the wait. I sat at the bar, and the service was amazing — super friendly and attentive, in both English and Spanish. Great experience overall.

We came here around 2:30pm on a Sunday, and ended up waiting around 20-30 minutes for a table. It also took quite a long time to get our food (30 minutes in between getting our drinks and getting our appetizers), but once the food started coming it all showed up in rapid succession. Things we liked: the crabmeat empanadillas were great -- freshly fried and delicious crabmeat. The ratio of crab to dough could be increased (reducing the thickness of the pastry would work). The fish taco was also tasty -- very crispy and tender. They don't have a ton of flavor, but the avocado hot sauce in a bottle at the table is incredible and made everything better. I liked the crabmeat on the crabmeat stew mofongo, but didn't like the mofongo (but we just don't like mofongo). I really liked the rice in the arroz con mariscos, but the seafood was overcooked. I got the shrimp soup/gumbo, which just tasted like a vegetable soup with overcooked shrimp. The ceviche was my least favorite ceviche on this trip. Overall the crabmeat was good as was the fish taco. But the seafood was overcooked, which was unfortunate.
