We went through the drive thru on a long road trip and were very satisfied. We have Culver's in our home state, but peripherals like sauces and the gluten free bun (celiac party member) are frequently forgotten. This Culver's nailed our somewhat difficult and long order the first time. Service was extremely friendly and very quick!
We did go inside to use the restrooms and the restaurant itself was clean and upscale in appearance. The bathrooms were also very clean, no automatic toilets which my skittish kiddo appreciated, and the water was warm in the sinks but not hot (important for kids especially). My only complaint is there were only 2 stalls in the bathroom so there was a short line for the ladies, but not a major complaint by any means.
Overall would definitely recommend.
