I've checked out Bob's and Cellar Homebrew stores and prefer Cellar. Their prices are better and they feel laid-back and friendly. They have a wide selection of ingredients, including a lot of liquid yeast strains and about two dozen hop varieties in the fridge, and bulk specialty grains and malt in the back, as well as bulk liquid malt extract for a good price. There's less equipment for big batches and all-grain brewing here than at Bob's. The staff are homebrew-knowledgeable and helpful, and the store has its own version of the loyalty card: Buy ingredients for seven batches, get the eighth free. Worth the drive, for me.
