We got free tickets to see Alton Brown last year. I did enjoy it, however if I had paid for my ticket I think I would have felt Jipped. Michelle Bernstein was the interviewer and she was not very good, especially with someone as witty as Alton brown. Then he did a cooking demonstration, of Crepes suzette which was non too inspiring. I actually prefer watching on TV.
AB and I attended the Bourdain show at the Arscht and thought it was a major waste of $. The interviewer was a local restaurateur who spent more time promoting his own interests than getting much out of the usually ribald chef-tainer. The cooking demo was nothing inspiring. The evening seemed geared to the See and be Seen Miami crowd - not even an amuse bouche to fans of the culinary arts nor hardcore Bourdainians...
Also - the venue was echo-y, empty and the acoustics DREADFUL.
Buy the DVD of his shows instead.
