I knew about this small chain as being mostly concentrated in the midwest. Imagine my surprise then when I happened to drive by one right here in Arizona! While Culver's is known for their Frozen Custard and ButterBurgers, I skipped dessert and just gave the Original ButterBurger with Cheese a try.
The burger was flavorful, with a flame-grilled patty that tasted like something you'd grill yourself during the Fourth of July. Fresh toppings, a decent bun. I liked it.
I decided to bypass the fries, even though they were crinkle, and give the onion rings a try. These were crisp and delicious. They are thin "beer batter" style and there were plenty in the bag to share.
Mrs. Fast Food Source tried the tuna sandwich. I am not a fish lover, but she said it was good. She liked the Texas Toast style bread and shredded lettuce.
Warning: Culver's menu is not that complicated, but the ways in which you can place an order are. You can order individual sandwiches, make your own value basket, or order a smaller SnackPak meal. This makes for more menu-staring for the uninitiated. Come prepared by viewing the menu here first.
