I've been to Patchogue, Montreal, Toronto, Cleavland, Myrtle Beach, Rehoboth, Baltimore, Louisville, Indianapolis, Nashville, Kansas City, Houston, Austin, Taos, Denver, Chicago, and a few other cities in the past couple of years. The majority of restaurants I visited had free refills for fountain drinks. The biggest places that I went to that didn't have free refills were places like food stands and what not, but that's expected.
