I've eaten here a couple of times now - usually after a round of golf north of Madison as we're trekking back home to the west side. It's a nice location and easy to get to.
The food is decent. Nothing like a good ol' hamburger to quench the hunger. The fries portions are nice. I like the frosty mug for your root beer (dine in) out of the tap. That's a nice touch. But overall, I think it's a bit pricey for what you get. The food doesn't blow away the competition. I never think to myself, "I need me some A&W food". Most times, I'll suggest having something else along the way, but my buddies like the novelty of A&W. You just don't see many anymore, so it's kinda cool to check in on them.
This location does a pretty good business (at least when I'm stopping in). It never struck me as very clean. While not "dirty", per se, you'll see straw wrappers on the floor and other untidy sights. I get it - you're busy and there's a lot going on. I can live with napkins and wrappers here or there, I understand - you'll pick them up eventually.
Will I go back? Probably. Will I be the one to suggest we go back? We'll see. I haven't yet.
