Like most fast food places, it's hard to rate a gas/diesel station higher than Three Stars, A-OK.
But, this Circle K is close, with Three and Half Stars. The location is also convenient on Greenway and across the street from a Safeway and it's gas/diesel station. I've grown amused watching how they try to stay in-between the posted price of Circle K and the ten cent discount offered by the tie-in with Fry's/Ralph's/QFC Kroger card. Sometimes it's only a penny or two. But clearly there's competition here, which is good for us at the pump.
This particular Circle K seems to be the least expensive of the bunch along Tatum. They also have a small center island Convenience store, but mostly I come here for the fuel. The station is not overly busy, which is another plus.
