Great if you want cheap gas... low on the ambiance scale.
Tony's Quick Stop is one of the cheapest places to get gas in town aside from Sam's Club (usually they are pretty close in price). Tony's is usually $0.10 to $0.20 cheaper than anywhere else in town. But, the trick is you have to pay in cash. They charge for any sort of plastic use.
It's a little ghetto... make sure you go during the day.
