We just went for lunch at Space 220 about a week ago. None of us asked for any substitutions so I can't really answer your specific question, but I did want to give Space 220 a little love. The atmosphere was very enjoyable and we took lots of pictures. The server was very attentive. We enjoyed our apps and entrees very much. My caesar salad was very good and my NY strip steak was also very good, but just a tad smaller than I was expecting. My wife and adult son also enjoyed their steaks. Son had the shrimp tacos and liked those as well. We were in and out in less than an hour which seemed just a little rushed. I would recommend this experience if you are going to be in EPCOT at meal time.
