Private room, N Miami Beach to Ft Lauderdale?
Okay, so no takers on your post. Could be there's a problem with the "high-quality, chowhound-approved food" and the "private room" requirements. I personally can't think of anything that has both, but I do know that Bimini Boatyard has a nice-sized private room on the water with decent food and they will work with you if it's available. Also, Sterling Worth Cafe in Plantation has a nice room (I haven't been there in years) in Plantation. The food there was also decent. Good luck and let us know what you came up with.
