Checked out this secret spot right after I saw the free Naked & Famous concert @ the Blvd pool. Crazy enough, I've passed by this place a majority of the time I've come to the Cosmo but never noticed it. The hallway is right next to Blue Ribbon, wedged right next to the restaurant on the right of it.
The hallway was clearly decorated with vintage album covers. At the end of the hallway there were 2 pinball games (a Vegas & Monopoly machine) & a Galaga! I got the white pizza and my friend got regular cheese w/ mushrooms. Initially, I didn't really like the taste of the white pizza($4), because whatever cheeses are thrown to them, but after it cooled off a bit, it was actually pretty tasty. My friends pizza had a nice crispy crust with little sauce but was still really good overall.
This place is a good & cheap spot to go if you're on a budget.
