GLBC is truly one of the best breweries out there. In my book, they make the best beer in the USA. The atmosphere in the restaurant is great. Yes, it often is busy, given how popular the place is, but you really have to just embrace the experience. There is a nice bar in the basement you can hang out at while you wait, or walk down West 25th and explore the lovely Ohio City neighborhood for a bit until they call you. I bring all of my friends from out of town to Great Lakes, and none of them have ever been disappointed! The gift shop is really cool too!
