I'm going to be in South Beach next weekend..2 couples..any suggestions? we'll be staying on 4th and Ocean..no car..I've been quite a few times and have always liked Nemos, Astor Place a few years ago, been to Tantra for drinks but never eaten..are these worth going to? Sat night we want to go out for fun atmosphere as much as good food..thinking of China Grill..thoughts? restaurants seem to come and go in south beach pretty quickly..any other thoughts...1 night we'll probably go expensive but moderate priced suggestions are also welcome. Thanks in advance.
