I live in Johnston directly across the street from one. Its always packed during the summertime pm's. 5 deep at drive thru and people parked everywhere. Lots of teenagers. This time of year it really slows down. I think they would benefit from a revamped food menu. They dont really offer much besides hot dogs and really really thin burgers. I think they would struggle in West Ames. I could see a hardees or subway going in and making it. I worked at the two Culvers all through high school and got to know the owners well. Flat out told me theres two key things it takes to make great $ in the fat food market, have multiple locations and have a great location and until the Westdale mall area took a dump they had two terrific locations for their stores.
A few years ago, 2 Sonics were built in CR. One on the north side and one on the SW side. Both in super high traffic areas. The owner closed them both down about 3 years later. There is no way they were lacking customers, so there must be something about the way the franchise is run.
