I have been to both and I agree with EMac in that TDB has an amazing view and decor. In my opinion, the salad bar is better at TDB; but the meats may be slightly better at Fogo.
Even though the meats are really the star of the show, I would still recommend TDB because it is far better than Fogo in all other ways: Salad Bar (more than salad bar -- great lobster bisque and MANY other items) view, decor, wine list. Finally, TDB may be a bit less expensive as well.
I haven't been to Fogo....but I have been to TDB on Miami Beach on several occasions.....I don't think you can go wrong at either place since the concept at both restaurants is very similar......The view that TDB has overlooking the marina and the bay is extremely attractive....and Fogo doesn't have that......I've entertained clients at TDB....ranging from 10-20....on several occasions.....and we've had great experiences at TDB......
