I've been to Club XS before and really enjoyed it. I recently learned about Surrender but according to Wikipedia XS is 8 times bigger. I thought XS seemed like a perfect size so does Surrender feel pretty small? The pics of Surrender look great and they seem to have top name DJ's. So what's the differentiator between XS and Surrender? In other words, why does Encore have 2 similar nightclubs and why would someone goto Surrender instead of XS?
