Was just about to post all of this information in a different thread lol. Yeah my guess would be Riptide Rescue gets moved to either the old Tidal Twister spot or the empty plaza between Rescue Jr and the arcade.
5,842 sqft sounds a bit small for a restaurant, doesn't it? With the 30' height limit I doubt it would be two stories either. I would love to have a sit-down restaurant overlooking the bay, but "Bayside Market" suggests it'll be another quick service or maybe just a grab-and-go location, which seems like an unnecessary investment. Unless... this is just the first stage in a bigger plan that would move other things around, close existing restaurants, and/or eventually create space for some new attraction.
