Also, you wouldn't happen to know what or where this "Mad Chef" character is would you? I've seen them referenced a few times in this comment area, but I haven't seen them...
I think he's just one of the random bounties you can get from the board in the town. I had found him originally in the dungeon thats straight in front of the town past the wall. I stopped going after those bounties since they were predictable and only gave like $50. They usually spawn on the first floor at the start. Haven't gone after them since v3.9.
