I have always found my flavor of the month(s) at a meet and greet. The evening ones are great, more like a party with smorgsbord, the lunches are a bit more like a business lunchen/seeminar. (yeah I meant that!). Imagine sitting around a table for 8 guests for an hour or two. Not only can you get to know somone very well and casually, but you can see others at the event, walk over, say hi, its nice and relaxed, and you can see if you have chemistry or not. The choice of restaruant is also always impeccable.
These events are great for the gals and guys, each of us get to meet and check each other out. I have always met at least two girls at one of these that I went out with soon after the event. It may sound trite, but it seems at these lunch events the ladies let down their guard a little and they all seem so nice, so friendly, and yeah, all so desirable! (Also, the girls eat free, I guess guys get to eat out after the luncheon.)
