OMG! really. I'm glad I posted this question. Let me cancel then. lol
If you go to the Disney app and go to the MK map under dining, Captain Grille's comes up in the Ariel's Grotto area. I thought that was the temporary location. You can tell I haven't been to MK in a few years.
This must be a glitch with the app.
Would love if someone can take a look and tell me if they see the same thing. Thanks!
