My plans for Halo got all messed up that weekend so I haven't been yet. I've heard it has a laid back world music vibe.
As for Hip Hop clubs, I've noticed Frequency seems to pack in a large crowd on the weekends. It's located on Pharr road above Cafe TuTu Tango.

I believe they offer more than just Hip Hop but it's worth a check :wink:
