I've been to clubs in Vegas, Miami and LA, with my Gucci sneakers - never had an issue getting in cuz of my shoes.
However, Cube thinks they are above everybody else. On my second visit here. While the person right in front of me just walked in with a pair of Adidas Stan Smith's (shout-out to Adidas and Kanye tho), when I got to the door the Bouncers told me they don't accept sneakers. Well I don't know if they have a thing against swagged out white guys, but denying a guy that looks like a trust fund baby is always bad for business.
Briefly: 15$ cover, rude bouncers, douche-bag alert, and no real MILFS in sights.
