Like everyone says, this is an unadvertised pizza "hole-in-the-wall" joint (if you can call a place with marble counters and tin ceiling moldings a hole-in-the-wall) on the 3rd floor of the Cosmo located down a long hallway between Blue Ribbon and Jaleo. You'll know you're going down the right hallway when you see a pinball machine at the end.
Honestly, this is the closest to NYC style that I've had since grabbing a slice before jumping through the turnstiles to catch the Lexington express down to 42nd St in high school. The thin crust, just greasy enough cheese, and sauce with faint chunks of tomato skin were all on point, fugetdaboutit. If you love you some NYC style, do yourself a favor and seek this joint out.
