I'm actually having my rehersal dinner at Carmens which is in the bridge hotel in boca. Great place but on the top floor of the hotel on the intercoastal. Which is especially nice for out of of town guests.
Renzo's has two rooms - one a dining room only and one a dining room with a bar. He often closes the dining room with bar for private parties and I've been there when he has hosted Dion, Don King, etc. The food is really good!!
