They do strike me as the type of food places with food that could go south very quickly.
You got the alternate dimension part right. The hotel's basically an RV in the shape of a hotel, and, sometimes, it leaves the driveway on trips to new (and debatably exciting) places. Like a mall. The driveway is an island, and there's a barrier around the island and some of the water not unlike a snow globe combined with an electric fence. There's one around the mall right now so we can't really go much farther than the mall and hotel. And it's a haunted hotel slash island so there's that to enjoy as well.
