Culver's is better than Michael's. I know that Michael's is local, which is nice, but it's just the truth that both the food and the custard is better at Culver's.
As other reviewers have noticed, prices are absurd. $3.69 for a small custard in a dish. I also wish that they had more toppings available than three. As for the frozen custard, it is good, but not as good as the custard I've had at other places. It really tastes more like ice cream than creamy frozen custard.
The food (basically cheeseburger, hot dog, onion rings, fries, cheesecurds) is also kind of meh.
I'll choose Culver's over Michael's nearly any time--the only advantage Michael's has is that it's nice to sit outside at the Monroe location.
