Ceviche is the new sushi — to the rest of the country, that is. When sushi first appeared in Miami, it was probably considered the new ceviche, thanks to our vibrant Latin American community, which long ago introduced the Magic City to this refreshing macerated seafood specialty. It certainly isn't anything new to Sam Gorenstein, who fondly remembers the cevicherias of his native Colombia. That's what led him, along with partner Roger Duarte (of George Stone Crab), to open My Ceviche at the southern tip of South Beach last year. "Roger and I really felt the need for a good ceviche restaurant on Miami Beach," the James Beard Award-nominated chef says. Prior to this venture, Gorenstein amassed a local fan base during his years heading the kitchen at BLT Steak. This take-out/delivery seafood venue, which also serves stone crabs and fish tacos, features a pretty simple system: Select your choice of seafood (shrimp, octopus, local fish) and then choose from six styles of ceviche, such as the version flavored with aji amarillo, tomato, onions, and mint. Or try the coconut water, avocado, red onions, cilantro, and lime. Maybe check out the Asian-style one with soy-citrus, ginger, red onions, tomato, mango, and cilantro. Popcorn comes on the side. It's $11.75 for a generous "medium" size and $14.75 for a large portion. Sure, you've seen it all before. The question is whether you've seen it this good.
