Stans Diner in Salem has the best Pepsi I have ever tasted (honorable mention Santaqueen in Santaquin), the Diet Coke at La Casita almost tastes like regular Coke. Barry's in Spanish fork is second only to Stans in Pepsi taste, really they are 1a and 1b. More often than not gas stations and restaurants have crappy soda, the worst is Brookside in Springville, it tastes like they use the soda and sewer pipes for the same thing. One of the exceptions, is the Sinclair in Springville next to two Jacks, their soda, for gas station soda, is great. Mcdonalds is on par with S&S Spanish Fork and the fast gas by Tesoro, very decent gas station soda as well.
