This is not the greatest pizza joint in Oakland, but you cannot beat it for the price. $5.50 for a customized 12' pizza is unbeatable, and the quality is almost as good as Lotsa Stone Fired Pizza, but at a tremendously lower price point. The staff are incredibly friendly, and the it is a chill environment - great for socializing.
What is also nice about this place is that, unlike other "build your own" pizza places, they do not limit you to a particular number of sauces or toppings - you can really experiment with the options and what the base price covers.
I did not try their subs or salads but they are also reasonably priced. I will update this review if I do try them.
The only drawback of this location is accessibility - it is underground, down a flight of stairs.
