This is always such an odd and generic question...obviously, it will depend on the people involved. In general, however, I would say that the first date is all about getting to know someone. Therefore, I would like to do things that give me an opportunity to have a conversation, with as few interruptions and distractions, as possible. I also associate food with pleasure, so dinner on a first date is probably the most ideal. I find that when I enjoy good food with good company, I am able to relax. It sets a mood that is comfortable and enjoyable. The more chemistry and conversation, the better! By the end of a meal, I usually know whether or not I feel a connection to someone.
