I've been twice. First time with ladyfriend who was chef, caterer and walking encyclopedia on organics and natural foods. She'd put anything in her mouth with glee, lie like a devil to the offerer, and give a hilarious private review as we walked away. She made the show an absolute hoot. Alot of fun can be had but my number 1 recommendation is:
1. Walk around a bit before you start cramming goodies down the hatch. Tempting to start cramming right away, but then you might start to feel, well, strange tummy rumblings and pass on some really good stuff later in the show.
2. It's wise to have water bottle, ginger ale or something with you in case of horrendous taste or someones S&M mustard - horseradish - pepper concoction. There's alot of 'em. And if you're the water carrier and SO is green and red and crying from above, there's a laff or two to be had.
After twice, I don't have urge to go again. It was fun, but wore off.
