In my opinion, if you or anyone in your family is a space enthusiast (but not exceptionally picky on technical issues), the group is likely to enjoy Space 220. It is one restaurant that I definitely want to have in the restaurant rotation when we go to WDW. My entire family group has found the food to be excellent, although your experience may depend on what you order, specifically. I think the filet mignon is very good. WDW restaurants that I would rate above it are California Grill, Monsieur Paul's (still closed, I think), and of course Victoria & Albert's, but that last one is wildly expensive so for us it is a less-than-once-in-a-decade experience. In my opinion, the food at Space 220 is on par with Jiko (though the two are quite different), Into the Forest (at Wilderness Lodge) and perhaps a bit better than Be Our Guest (just recently). Skipper's Canteen is fun, and we like the food there, but it offers an experience of a different type. I liked the food better than at Cinderella's Royal Table (heresy, I suppose). Citrico's has been variable in our recent experience. I thought the elevator ride up at Space 220 was imaginative and amusing. It seemed to me that it was faster going up this year than last, but equally fast going down both years. We enjoy the variety of ships and space walkers who can be seen at the large viewing windows. I think the experience is overwhelming for a very small number of guests; we noticed that this was true for one person during our two visits, but I don't think claustrophobia will be a problem. The parts that could be called a tunnel seem no more difficult to me than the tunnels that connect concourses at O'Hare.
