Three's a Crowd

Okay, I had an idea the other day that needs brainstorming. The concept is a restaurant called “Three’s Company.” It’s a restaurant for couples. No table seats more than two people. The menu is built around meals for couples. The ambiance is romantic. And so on.

Obviously I haven’t taken this idea much beyond the basic concept. What do you think? What could a restaurant do to cater specifically and exclusively to couples?
