After a long night of clubbing at Marquee, nothing beat the secret pizza place at 5am. The wait is long and it will take hour(s) to get a slice of pizza but it's worth it.
Better yet, if you have a room at Cosmo, just order the pizza for delivery to your room. It will take an hour or so but at least you can relax in your room while you wait for pizza.
Yes, it's secret and it's hard to find but once you find it...PIZZA!!!
