In the Manhattan board there's a short thread about L'Impero, which got me thinking about what makes a restaurant 'romantic'.
To me, so much of this depends on mood. The most romantic meal I ever had was at a not-very-good restaurant in Manhattan. Everything went right. We were recently engaged. The couple at the next table was friendly, but not too friendly. The waitress brought food at just the right times, and poured wine at the right times, unobtrusively. I don't remember what we ate.
I've eaten at restaurants billed as romantic, and not been impressed that way at all.
So, what makes a restaurant romantic? Can a restaurant make you or your loved-one more romantically inclined (other than just being happy to be with him/her, eating good food). Is it the food? or what?
