Have a craving for seafood? This is the perfect spot to satisfy it. An original Mexican oyster bar (transplanted), Ostioneria may be hard to say, but it’s worth it to your stomach. Try the ceviche, or the oysters, or the red fish, or the seafood platter, or ... It’s all fresh and fantastic.

For the ostioneria near you, look them up in the white pages (16 names/locations listed) under “ostioneria” (the type of place comes first, the name afterwards in proper Spanish). Or, the yellow pages
under restaurants, Mexican/seafood.
