What a cool experience. Really enjoyed the food, the drive in concept and fast assistance.

Just stopped to get a drink. Love all the options. They made the drink as ordered so I guess we're good. Onward.

I’ve had a couple of goofed orders, only on burgers now and then, but for the most part they get everything right and paying is easy on the monitor. I like the “round up the amount as a tip” option. I’d never tip at a fast-food or Starbucks counter, but I’ll give these carhops my bit of change. I hope it goes to them! There aren’t many places that serve breakfast all day where I am. At least not fast-food places. So I appreciate that they do. Carhops are very polite kids, ditto drive-thru.

I used to like this place until my orders started being not exactly what I ordered. This is why I rarely eat here. Today I ordered a Jr bacon cheeseburger that came WITHOUT THE BACON. The chilli cheese fries were good and so was my corndog. But I was very disappointed with my NO BACON CHEESEBURGER. Maybe I’ll try again next year. Maybe not.

You can never understand which stahl you are in. Is it the pole? They need to fix this. This is a corporate problem that they leave to each location to handle the frustration. Corporate needs to fix the inconsistent marking of the stalls.

This sonic location has become horrible. Been here three times over the last two months, each time the food has been extremely delayed. Last time (today) I arrived at the pickup time. Five minutes later after the screen said it was coming out, asked them about it, they said it was on its way. Another five minutes later I asked again, said it was coming out. Four minutes after that I called, said it was coming out. Ended up being 15 minutes late after the pickup time, with an attitude about it when they brought it. Don't go here if you have any choice.
