Wingstop on S. Mason in Katy is fantastic. My husband and I are, embarrassingly, regulars. We eat there once a week or once every two weeks. He's just a wing-a-holic and I'm a sucker for a pouty face!
I always call ahead and order the same thing every time - 20 Original Hot (bone in - not HOT HOT, just nice), 2 Large Fries (nicely seasoned), 1 Large Ranch Dip. This order costs about $17. Its more expensive than your other fast-food joints but worth it. Its the perfect quick dinner for chilling in front of the TV. The wings and fries are always good. In all the times we've had food from Wingstop we've never had a bad batch or a mixed up order.
Usually the service is very good. Only once was I put on hold and forgotten about. They often get very busy on Friday and Saturday nights. They do deliver but we always go in and pick it up because its so close to where we live. It doesn't matter how busy they are though - your order will always be ready in 14 minutes (never 13 minutes and certainly not 15!). I particularly like it when you get a staff member on the phone and they say "OK that'll be ready in ... oh... lets see... lets say 14 minutes." as if just this once, it *might* have been 15 minutes!
Wingstop is a great little place to eat-in or take-out. The inside always looks clean but there's nothing as satisfying as eating wings and their yummy seasoned fries in bed with Lost on the TV!
