Prolific Oven but since neither of us wanted to get lunch there, we opted for Premier Pizza instead. Both are located in the same strip mall and we both had meetings until noon so we didn't arrive until the height of the lunch rush.
Premier Pizza also specializes in corporate catering and it's how I heard about them in the first place when my old company ordered in for lunch and I tried out their pizza. They have four locations to serve the South Bay and Silicon Valley. They're a good option when you have to feed a lot of people at once and the different choices of toppings means you can easily accommodate both vegetarians and meat lovers alike.
