I eat here at least once a week. The atmosphere is laid back, and the owner is a really friendly guy. The patio is pleasant and dog-friendly.
I am a strong believer that the most important element of pizza is the crust. The crust at Shorty's is fantastic. It is always chewy, tender, and crisp--all at the same time. This place is exactly what Waco needs. The fact that Pizza Hut has a higher ranking on Wacofork is a travesty. This place seriously has some of the best pizza I've ever had.
Prices are reasonable and there are some pretty good daily deals. As others have said, Shorty's could improve their draft beer selection. But seriously, this is the place to go for pizza in Waco.
