I need a recommendation for a dinner for 2 in Manhattan - am going with a business collegaue who is not particularly adventurous. Previously we have gone to Mesa Grill and Bar Americain, both of which he liked. I don't want to go back to B.A. and I would go to Mesa Grill again except that I'd rather go somewhere a shorter walking distance from our hotel in Midtown (Madison and 52nd). Any suggestions?
