Very authentic, and extremely cozy. I recently found this gem randomly while looking for great Mexican restaurants. It's now easily in my top 3.
I had a delicious seafood dish called Del Mar. It was a mixture of shrimp, scallops and crab. Then they added white wine and cream sauce with chorizo sausage. It was topped with roasted poblano peppers and onions which gave it a nice spicy finish. I will be telling many friends about this place.
