Miami, not known for its raw-bar diversity, nonetheless has had a stalwart purveyor in this restaurant and its sister in Coconut Grove. But the South Beach locale usually plays second fiddle to the Grove location in the popular imagination. We don't know why. The South Beach spot is wonderfully situated on the water by the Miami Beach Marina, a perfect place to catch a sunset. And this spot doesn't disappoint the tradition of raw bars as a happy-hour destination. From 4:00 to 8:00 p.m. a dollar will get you two peel-and-eat shrimp, or two fresh oysters, or clams. Stone crab legs are two dollars each. And drinks are half-price. The seafood is specially selected for freshness and quality. The raw-bar line can get pretty long, but it's worth the wait. Monty's is open from 11:00 to 1:00 a.m. during the week and from 11:00 to 2:00 a.m. on weekends.
