Upon entering the first thing you'll notice, aside from the overwhelming smell of the fryer is that this place is cash only; so plan accordingly. I ordered the What-a-cheeseburger, small onion ring and small Pepsi. My wife ordered a fish sandwich and small Pepsi. I noticed that the cashier was focused on getting the order correct. No small talk, no pleasantries, but about business. He wasn't rude so I can respect that.
After a few minutes our food arrived. My burger tasted decent. I know you're probably looking for a more descriptive word, but decent is the only thing that comes to mind. It wasn't horrible, but of course I've had much better. The onion rings were pretty tasty. My wife enjoyed her fish sandwich.
Overall, this place was ok. I think most love it for nostalgic purposes and I can did it. If I'm ever in the area I might drop back in but I don't think I'll make a special trip here.
