I was here for a work event, so we had the whole club rented. The event was solid, with a live band and plenty of good dancing grooves.
The entry is cool, reminded me of Han Solo being frozen in carbonite, a bit random, but you will get it when you walk in.
I really like the way this place lays out, big open dance floor with plenty of seating around the outskirts. They even have an outside area which is nice to go and catch your breath. The staff was on it, plenty of people helping to ensure we had a good time.
XS is classy, and not too over the top, expect Vegas prices on drinks. My group had a blast, fun night at XS.
