I have a Slurpee addiction, so I've hit up every 7-11 that is within a 5 mile radius of my house. This location is alright. Nothing spectacular about it. It seems like they are always having issues with their Slurpee machines, and some flavors are always shut down. Parking here is a bit rough as well - a lot of traffic seems to go by the area on Horizon, so if you don't time your stop just right, you will be waitin forever to turn left.
The staff has always been friendly. 7-11 is great for a quick stop if you need something, but don't expect phenomenal prices or anything.
