I was here before the supposed end of the world, and it seemed like everyone here was having a great time. My gf got a tip from her promoter that got us to get in for free, alongside the complimentary drinks that they offered just before midnight, so it was pretty cool to come in hang out for a bit.
Blush is really small in comparison to XS and Surrender. Blush doesn't have a dance floor, just walkways in between the tables. You can try to dance in those areas, but you'll end up looking kinda awkward dancing in the limited space. The music seemed to be mainstream, with less emphasis on hip hop. We only stayed in there for about 30 minutes and ended up leaving to meet up with the others outside that couldn't get in.
