Mama Melrose dinner was good. The new low allergen menu has plenty of options (more photos of that here )
The dinners we ordered were good. Not rave reviews, but good and we enjoyed it. The dessert was good if you only have a gluten allergy. If you have a dairy allergy, Disney seems to have said "Your problem not mine" these days...
But at least this dining establishment had an option! Some did not.
We would recommend Mama Melrose, though, for the entree options. Full review here. Enjoy!
