I've been to the Heist Brewery three times now and have brought others from Chicago. Everyone liked the place- but they liked it for the food.
I think the food is good. My wife and I like the wings and the tater tots. I could seriously eat about 30 in one sitting if I were allowed. The tots are really good. I've had nearly everything on the appetizer menu and have been thrilled with almost all of it.
The beer, well for a brewery, the beer just isn't all that great. I've tried a couple of flights of beers on different trips. Both have been disappointments. I drink it because I'm at a brewery, so its what you're supposed to do but they aren't all that good. The Heist offers sodas that they brew as well. My wife tried the orange soda- average at best.
The atmosphere is cool though and each time. The service has been great each time as well.
I'm happy with the food. I'm disappointed with the lack of flavor in the beer. Its a neat place though in a cool neighborhood.
