Of that list, if you want to make friends, I suggest going to these bars (in order or anecdotal popularity):
1. Shipyard [Although I disagree with the best cocktails in town. That can be found at Backyard Bar where David makes them.]
2. Mr. T
3. Madison
4. Stone & Wood
5. Knights
6. Friends
7. One the Way [Which has two locations, the other is very close to Knights but is difficult to find]
Bitburger & Bacchus are mainly restaurants, so it's a little bit more difficult to mingle.
Tang Club, 88 Club, Phever, Phebe, SOHO, and MGM are clubs. I do not recommend going to clubs to make friends simply because is too damn loud and chaotic to talk to anyone. It's a place to go after the bar or a later dinner.
I'd definitely say that the first place to meet new people is Shipyard and go from there.
