To give you some thoughts: I've never really heard of anything like this. I think the trickiest part is going to be defining the "experience" of a restaurant, not the least of which because different people experience different restaurants differently. Pandora has an advantage in that the number of other people listening to a song has little bearing on the sound of the song, but the number of other people eating at restaurant (as well as their loudness, fashion, etc) can have a significant impact on the experience of a restaurant. I have actually kind of wished for something like this before though. I was trying to search by the absence of a particular feature on Urbanspoon (namely family friendliness; it seems every restaurant in the town I was looking in is entirely filled with youth soccer teams) and found I could not do it. This also leads to my next question. Urbanspoon doesn't have an API. Yelp is no match for Urbanspoon. Where are you getting your data, if you wouldn't mind divulging? I'd love to know how things are progressing. Do you have a blog or something going where I can follow your progress?
