Fair question! I ran it last night and we all had a great time. Since it's only two pages, it definitely requires a lot of GM improvising. All of the important stuff is there, but it's up to you to decide how they get to the dungeon, how to present their challenge, and add personalities to a lot of the characters they'll run into...and also how to deal with players doing things not accounted for (for example, my players murdered the insane chef trader, so they only got the item he was showing them when he died).
I also added a a panel of goblin "judges" who tried the food before Bakto, to illustrate the graphic, lethal effects of many of the ingredients (which Bakto of course would be immune to). Conveniently, my group just happened to make the same number of dishes as there were players, so each was judged individually. Instead of just the chicken, I gave prizes for 1st, 2nd, and 3rd place, with 2nd and 3rd being magic items from the dungeon that they didn't come across.
But at the end, they traded in their prizes for the mystery box, which contained...invitations to season two!
