Pezcalato Peruvian Restaurant If you think ceviche means rubbery chunks of mystery fish in a lime juice marinade, Pezcalato is going to spoil you. When you order ceviche at this mom-and-pop Peruvian restaurant on Richmond, you have to specify your fish. There's grouper or snapper ceviche ($14 a plate) or tilapia or catfish ceviche ($12 a plate). The fish tastes like it's been tenderized; it literally melts in your mouth. Every order comes with plenty of mixto, a delectable mélange of tender octopus, squid and mussels in a lime juice marinade. The seafood is covered with flecks of fresh cilantro ground so finely it resembles a pesto, and it comes to the table South American-style with a slice of cold, cooked sweet potato and a little round of corn on the cob. When you're done with the ceviche, drink the marinade. Called tiger's milk in South America, it's said to be a hangover cure.
