Lots of comfort food you can't buy elsewhere. Desserts are primarily frozen and delicious. Lots of variety with drinks and burgers, hot dogs,

Ordered through the drive-thru which is a bit funny because it's a sonic but I placed my order pretty easily but the wait time was a bit more than usual considering I didn't see that many people parked around. Enough negative though, got my order entirely correct. The burgers weren't greasy and bun wasn't soggy and it tasted pretty good. The fries were probably the best part, they're not stingy with the salt or the ranch. Overall it was a pretty good meal...
