We had some surprisingly decent pizza in this small town west of Liberty and Roscoe, east of Binghamton, right off 17. I don't remember the name (maybe Little Italy?) but it's easy to find. It's right on Main Street, just a few doors down from Rite Aid and the car wash and across from a fancier place called the Bluestone Grill. The big pies looked like they'd been sitting for a while, so we ordered "personal" pizzas, which came out fresh and tasty. The sauce on my son's pasta seemed to be homemade,too.
Not worth a detour, but handy to know about if you're driving through the Catskills.
