What a fantastic idea . . and it does seem like a great fit for Grace's foodie side.
GPN even have a ready made theme - 101 ways to use cheese and chocolate. :D

Since article didn't say I did a quick search .. the E&amp;G is separate from tickets as you'd expect .. .you have to have paid a $25 fan membership fee to try for one of the (usually) 150 spots .. if you get in then the pass is $50.  
I think that is pretty reasonable considering I know of artists who charge (know of people who paid $150 in one case) for M&amp;Gs that are nothing more than a few minutes of chit-chat and a photo op.
