Was at Surrender for MDW to see Calvin Harris, bought prepaid tickets which got us in fast, despite arriving at the scene at 11:30pm. After entering the club hassle-free, the excitement quickly dwindled. \nThe concept of having 80% of the club outdoor is nice, however the implementation was poor. Calvin Harris was playing at the indoor portion of the club, except no one was allowed on the dance floor except if you purchased a $3000 table. Why even let people in if you don't allow anyone on the dance floor? Waste of money on cover, and it wasn't like the cover was cheap either; $100 for guys and $40 for ladies. Go somewhere else to have a  good time.
