Linda,
That is not a problem at all! There are plenty of good quick service restaurants that are also indoor and air conditioned. Here are my swapping suggestions, based on your initial list;
Tangierine Cafe: While it has interior seating, it is usually open to the outside, so it won't feel very air conditioned to your friend. Go instead to
Les Halles Boulangerie & Patisserie.
Gaston's: With only a few seats, and a pretty short menu, I would instead opt for
Columbia Harbor House or Cosmic Ray's Starlight Cafe.
Rose & Crown: Assuming you mean their fish-and-chips window, then you should instead go to
Sunshine Seasons.
Wolfgang Puck Express at Marketplace: This one used to be a no, but is a yes to indoor seating since it's recent renovation.
Flame Tree BBQ: Go to Restaurantosaurus, since all of Flame Tree's seating is outdoors.
Sunset Boulevard: Go instead to the
ABC Commissary, a hidden gem in Hollywood Studios.
I hope this helps? I think it will make your friend happier, and you should still get some good meals. Thanks for the question!
Have a magical (and delicious) vacation!
