When I was in Cali last weekend I had my favorite called Frantones, oh my god. I spent 80 bucks just so I can bring 3 pies back here to AZ. Guinness has no better pizza compliment in my book.
If anyone is ever in the Los Angeles area, look up Frantones Pizza, they're in Cerritos, Norwalk, and... somewhere else. Get you a large pizza with every meat, peppers and mushrooms, a 12 pack of Guinness and thank me later.
