Pupusas (it's a Salvadoran food) I haven't had them since I was a kid, and don't quite remember what they taste like but I know I LOVED them and would love to try them again some time
Craving a certain brand of chocolate.. the annoying thing is that it's only available at the fanciest grocery store in the area, which also happens to be the furthest away (but still a pretty short drive/walk all things considered).
Curry from a specific Japanese restaurant my boyfriend and I go to on special occasions. It's so good, but we can't get it very often since it's a bit pricey to eat out.
