The entrance is guarded by a couple of security men that should learn how to welcome people. I went there by myself around midnight, the place was almost empty. At first they asked if I had reservation, it was compulsory for getting inside. Then, they said that there was dress code, while the clients besides them where dressing basic dark t-shirt...
But worst that all, I was disgusted by their bold and rude attitude, like if they enjoy to prove their useless "powers" over clients and make fun of them - real gorillas are more kind.
Definitely not suitable for foreigners.
The reply from the owner ("You are wrong"), is self explanatory... as usual they don't bother to understand what went wrong with their staff, they just blame the (missed) client.
