I went last year and had a pretty good time with it. Going again this year. Caught part of Guy Fieri's show last year and it wasn't much, so I'm hoping to see Alton Brown this afternoon. Good chance to sample a bunch of snack/appetizer stuff, and I'm hoping to make it to the beer and wine sampling areas today as well.
I love IX Center shows. Growing up in that area, I've gotten to see tons of cool events there. Sucks they're probably going to gouge me for $25-$30 a ticket plus $8 to park, but you only live once, right?
