How about Alhambre, t is pretty hard to beat for spectacle. The menu is pretty easy to navigate and while most culinary enthusiast probably prepare many of the menu items at home on a regular basis, hummus and baba ganoush are adventuresome and rewarding for some. The steak was certainly good enough and the menu in general is simple enough for anyone to find something they will enjoy.
The space is pretty exceptional and made me think of Ricks from Casablanca or what it might have been like in cuba in the 50's.
I have been to Carnival, Nacional 27, and Zed (when it was still Sal and Carvo) with groups of diverse non food oriented people. In each instance I found the food to have made an impression but it was Alhambre that made for the most memorable experience with the least need for forced conversation - if not the best meal.
