The Case of the Missing O.D. is set in an eye doctor’s office where your goal is to locate the missing optometrist. Combo & Key initially started in an actual optical store, but they’ve since moved to a dedicated “escape room” location. We had a good experience with Combo & Key, though there is too much going on for a two-person team. They have recently opened a second room and we look forward to checking it out. See below for the full review.
