Had Goose Island's Marisol the other day (it was a collaboration with Rick Bayless) http://www.rickbayless.com/news/view?articleID=179
It was pretty bad. I don't know about anyone else but I can't drink 312 on draft, it always has a skunky taste to me, and I found this to be very similar. It had a lot of nice elements going for it, but nothing ever popped. I had Goose Island's Madame Rose which was a collaboration with the Bristol last week and that was freakin fantastic! Other one I really enjoyed recently was Petrus's Aged Ale. Very sour, very very good. There isn't much about it that makes you think beer.
