We couldn't find any info about this event anywhere, so I wanted to review it so people know what to expect. There are a bunch of different exhibit halls at the Dow Center, and Brew Ha Ha uses 2-3 of them. You walk in and get your tickets, and there's a coat check if you want,, and then there's one hall with beer in it to the left and one to the right. The comedians are in a separate theater, and they did shows at (I think) 7:00, 7:15, and 7:40, and then again at 8:30, 8:45, and 9:15, or something like that. So you walk around tasting beers, and then you can get a full beer and go in and listen to the comedians. You can buy additional drink tickets for $1 each, but (I think) you have to buy them in packets of 10. Most of the samples were 1 tickets, but some of the high-octane stuff was 2 tickets. The full beers were 5-7 tickets.
There was a bar that we didn't go to (we had already paid for beer, why pay extra?), and there was a snack bar where you could get ballpark food -- pizza, hot dogs, popcorn, etc. If you want something more substantial than that, eat first.
As for the review: it's a crazy mass of people like any beer fest, so expect long lines and a bit of jostling. Beer fests are always like that; you're being unrealistic if you expect anything else. There were a lot of good beers to try, but one important thing to remember is that it's not like the festivals that the MI Brewers' Guild puts on -- the people pouring the beer are not from the brewery, they're from the Dow Center. They are not going to know much about the beer beyond where the brewery is located. In some cases, they might not know about beer at all (one woman didn't know how to pour a stout and I ended up having to wash my coat later).
The comedians ran the gamut from OK to hilarious. I saw that in previous years there were complaints about the sound, but we could hear just fine.
