Dropped to four stars. Still the best fast food restaurant, but I had problems in two different restaurants, wrote to corporate headquarters and never received a response. Also they're not changing their deep fry grease often enough, so we're left with rancid oil aftertaste. We love you, Culver's. Please fix these problems. Please note: this review applies to multiple locations throughout southern Wisconsin.
