The pizza at FAT's is REALLY good... however the service is pretty terrible. I have been there on numerous occasions and I have had to wait for a waitress/bartender to acknowledge me for way too long. The bartenders seem to be off in their own little world - flashing and kissing each other and yelling semi-obscene things... which is fine for them, I don't really care about that stuff, but if I have to witness it, I'd like a beer, please.
Also, the patio is nice, but a little too small for the claustrophobic in me.
