The last time I had an actual meal on an airplane, it was almost certainly a frozen Banquet turkey and dressing dinner in a different package. That doesn't mean the novelty of eating inside an airplane has worn off, though. I'm currently planning a trip to Zurich just to eat an "in-flight" meal at Runway 34, a restaurant inside an a 1950s-era Soviet Ilyushin IL-14 airliner! See more pictures at Dvice.

Unfortunately, I haven't been inside it.
