I've been here a couple of times and I don't get what all they hype is about by other Yelpers. I just ordered and consumed a Juicy Lucy burger and sweet potato fries. The fries were ok and the highlight of the meal.
I get the stuffed burger concept of the Juicy Lucy - I've even been to a joint called the Juicy Lucy on the Wisconsin - Minnesota boarder.
The Juicy Lucy I had at the Baldwin Grill was over pattied, over cooked with an off-putting texture. The beef itself had a sort of meatloaf flavor. It wasn't a fresh a fresh tasting burger. It was anything but juicy.
Others in my group ordered burgers and said they were OK, but did mention that for $8-10 a burger the burgers seemed a bit pricey for an unremarkable bar burger. All of this said the place is packed on a Tuesday night.
Like I said, I've been to Baldwin Street Grill a couple of times - no need to come back for food. If you want a great burger - the best burger in Madison, head over to Player's a few blocks away.
In closing - I hate to pan a locals joint. I love locals joint... I'd say it's safe to say Baldwin Street Grill is fine if you are after the quintessential Wisconsin bar experience. Come on - they have a meat raffle - that's a plus. As I write this Hendrix is playing... I'm really feeling badly the food wasn't better.
