There are samples of the dish, there is no wine anymore (a couple years ago they used to give you a wine sample). We did a couple last trip and one was excellent, we're returning to see that chef again this year. The other sucked so much. We went to a crab demonstration where they spent the ENTIRE time making pasta (ravoili maybe for a crab filling?), our gluten free fam member loved that (especially when they slammed gf a bit "you just can't make good pasta with gf" or something like that)). No wait, I exaggerate- they did say "taste the crab first to make sure it's not too salty". So, they did give us a few words not on freaking pasta. What exactly you're supposed to do if your crab is too salty they didn't cover.
As pissed as I was about the crab demo we had a great duck demo and that's the chef we'll return to see, and heaven help us we're trying a new one as well. The value isn't great or even good TBH, the sample is equivalent to what you'd get at a booth, but we do like the time off our feet and usually learn a little something about cooking. I like to grab a champagne/wine to sip on during the demo
