42. A sushi bar
Surprisingly, more and more men start loving sushi. And nowadays, when you pop into a nice such restaurant you see more men and women. Some of them are having business dinner, others are meeting with a friend, but there are those, sitting at the bar, having dinner after work on their own - and those are you could easily sit next to and perhaps strike a conversation if you feel like it. Or he'll be the first to talk, guys are usually like that - they catch your eye and they just start talking to you.
