Crickets is the first place I visited in Waco, and I have gone back regularly since. I've only lived in Waco for about a year and a half, so I can't speak to a decline mentioned in the other reviews.
This place is really a bar. Don't go in here with an unrealistic expectations of how good pub grub should be. Stick to the burgers/sandwiches. As far as appetizers check out the loaded cheddar fries. The nachos are also good, as they make real, individual nachos. That is, they don't just pour cheese sauce on a pile of chips like it's a tortilla-chip pie, which seems to pass for nachos around here.
But let's get to the real reason to go to Cricket's: the beer. This place has the best beer selection in town and generally the beers are very fresh. Good smattering of styles and regions with a thoughtful emphasis on central Texas beers.
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.
