Mi Compa Chava
Prepare to wait for a table at this hugely popular seafood restaurant a couple of blocks from Jardín Centenario—it's known for serving big, gorgeously plated portions of sublime ceviche and aguachile. There's also a great variety of raw bar options, including oysters on the half shell, as well as fish tacos, smoked-fish pâté, seared bluefin tuna, and more. The original location in Roma Norte is similarly outstanding (and also always packed).
