Brew and Grow in the city isn't worth the effort, except POSSIBLY on a Saturday. I've been there six times, and only twice was able to find what I needed, one of those times for bottles. their hops supply sucks, and their yeast isn't far behind. I've also heard from others that their in-store grain mill doesn't do a very good job, either.
All that aside, I was able to go in on a Saturday, the only day that their brewer apparantly works, and had a nice talk, and got some good info, along with a couple of samples of his stuff.
