After living in Texas for a few years, I was pleasantly surprised at how quick our trip to DQ was.
Over there, it's not unusual for a short line at Dairy Queen to be 4 cars deep.
My wife and I were out running errands and she wanted dessert and this was the first place we saw so we pulled in. Only a few cars, quick service, friendly lady at the window. We were in and out of that parking lot in under 5 minutes.
My wife got a turtle pecan blizzard without chocolate sauce. Not a super complex order but you'd be surprised how often this one gets messed up at Texas locations I've been to. It came out perfectly mixed, just the way she likes it.
This is definitely a solid location.. Stop by sometime!
