Unfriendly staff, I fall down in their floor because it was greasy and the staff they didn't care to help me thanks to a customer he helped me.
So I left on rush when I paid because I was hurt, next day I found out they charged more and I called many times many day no one answer my calls or my messages I left.
I was lucky didn't break my leg only bruised, horrible place will never go back there.
