Here's one that I'll bet you don't usually see in food blogs: hospital food. (No worries; I've been discharged.) What struck me about this wasn't so much the food itself, but about how similar everything was to airplanes. You get your choice of a Western vs Asian meal, you get it served on a tray, and it comes at a preset time. Moreover, you have bedside controls to recline your seat, change TV channels, and even call the attendant over. Scary!
