I went to the Friday session, my first time there. It was not as bad I had expected, based on what others have said.
Pretty good service and food selection, fair prices. Lineups were manageable from what I saw, except for the washrooms at one point.
It does have a frat house vibe, with many people wearing silly hats or matching t-shirts, with drinking-themed slogans. The 10-man DWO (Drunk World Order) group stands out.
The most interesting beers were in the Canada 150 Pavillion. Getting $1 pours of La Buteuse and some of the other Quebec treats was a highlight. I got to try a bunch of new beers for $1 each, and some were pretty good. Stouts were hard to find.
