I come here for one reason and one reason only. Milkshake specials. They're the right mix for a shake. Thick and creamy. And the right price. 99 cents for a good size portion, at least an avg of 2 serving sizes.
Other food is pretty decent, too. Reminds me of fair food with the taste and variety. And who doesn't like a good old fair with the rides and the junk food.
Even though I love the tandem drive thru, you've definitely got to watch out for the other side. Once people have their good greasy food, they're gone quickly.
