We overnighted in Monticello after a fairly long day's drive and wanted an easy option: the Wagon Wheel certainly fit the bill. It's a very casual pizza joint, operating by a young and friendly crew and they do a pretty decent job of it.
The menu is actually reasonably varied and the prices are fine. The decor and ambiance are basic in the extreme, but you do get to observe some small town comings and goings and so that's interesting in and of itself.
It's alcohol-free, so just be aware of that and they do - obviously - offer take-out. It's probably more accurately a 7/10 experience - I have to deduct a point for no alcohol - but as long as you go in with the correct expectations than it's a more than acceptable option.
The acid test (that is, would I return): Sure.
