Green Eye, under the Blue Line On Western by Armitage has it too.
My two cents in the value of brewing locally: While it is entirely true that just because something is produced locally does not mean it is inherently better. However, why is Portland such a great beer town (I'm moving there in a month, actually, and that is one of the perks of the relocation)?
When a community of artisans spring up, whether it be wine, beer, food, whatever, the closeness of each other causes everyone to rise. It's easy being the only game in town, and you don't have to try as hard (and I'm not ripping on GI). But when there are four or five games in town, you have to strive for excellence in a way that benefits everyone.
When you have a number of people doing this, it creates not only an artisan community, but a consumer community as well. People come out for this type of thing. People talk about it, share their favorites, their likes and dislikes, which furthers success.
Why is Chicago such a good food town? How can it support something like LTH, populated by maniacs who chase down quality and strike down mediocrity like the X-Men fight crime? Because we have a community here. It's not chain restaurants, it's not places run by celebrity out of town chefs, it's places like Lula Cafe, Blackbird, mado, run by people we live next door to, and know, and encourage and nurture. We create this community, and its success is driven by its locality.
So, bravo to more breweries here. If someone opens one, check it out. Support them. Because if they do well, someone else will see it is a viable business, and open one, and so on and so forth. Make Chicago as much a beer town as it is a food town.
