I think most of the eating areas in Tomorrowland are rather boring. I have an idea that would make it at least late 21st century. I don't think it would ever be made due to the cost, but whatever. Please don't put anything about it being impractical, or not cost effective, or whatever.
You enter the building and inside the walls (TV screens or projections or something) show a panoramic view of space and the rest of the "space station" you're in. Imagine you're inside one of those space mountain-esque space station things like they have in the murals on the walls in Tomorrowland. You are in a spire, so if you look you can see the rest of the space station as well as the stars. You notice little claw things are carrying around baskets with food in them and dropping them down at tables.
As you sit down you have in front of you a touch screen table. On it you have a button that says "menu" and it opens a menu when you press it. You click what you want, and you can have "settings" for everything, such as if you want ketchup or mustard, or lettuce and tomato.
After you press order you are asked to place your credit card on the table and it reads the credit card. Or it could have a slot for putting in credit cards and money. It then says "while we prepare your meal, here are some games and videos" and you can watch videos about the Disney parks, watch Disney shows, play some basic games, etc.
When your order is cooked it is placed in a basket and is carried out of the kitchen. Here is a basic outline of the basket and hook mechanism.
Overall restaurant. Red lines are carrier tracks, and there would likely be more tables. It's just a rough plan.
Basic basket design (the hole is where the hooks in the carrier go through to carry it.
From there you eat your food (you can still play games while you eat).
