This was my first time at Culver's. I had a butter burger with cheese. It was very good, I thought similar in taste and quality to In and Out.
The cheese curds were fantastic, I highly recommend them. They taste basically like a good mozzarella stick appetiser at other restaurants.
Also had a cookie dough concrete mixer. It was as good as advertised. Thick and tasty.
Only detractors to coming here-cost and high fat/high calorie. High fat/high calorie goes with any fast food though. The cost however is much more than a typical fast food place. $24-26 for two of us getting food basket combo and two med concrete mixers. So not extremely costly, but more than typical fast food.
