I think the podcast was sometime around the end of May of 2011.
We've been to the fork & dine and really enjoyed it. It's basically the same kind of money you'd spend to go to dinner at most casual dining places. The free drink refills are great, and the serves we've had have always been really attentive and polite (even more so than I typically see at a lot of outside restaurants).
The tickets are based on reserved seating in a specific spot, so I'd recommend buying tickets online or going to an off-time show (like a weekday around lunchtime).
