Secret Pizza isn't so much a secret anymore. Especially if there are over 3000 reviews and a long line. Who doesn't want NY style pizza at 4am after a night of partying? To find this place, you have to go up to the third floor of the Cosmo. There's no signage but there will probably be a line of people. You go through this long corridor decorated with photos of old timey musicians and celebrities of the past (maybe they were album covers). Once you get to the front of the line, you can choose a slice or a whole pie of whatever's available. They list the prices but they don't list what flavors they have since it seems to keep changing. Vegetarian combo, white cheese, pepperoni and sausage, etc. the white cheese pizza is AMAZING. Slices start around $5 i think and they are big slices, so one was plenty for me. I think they're open until 5a when most other places at the Cosmo are closed, so it's a good and sometimes the only option after the Marquee closes up for the night...
