Banh mi Madrid?
I have been in Madrid for a while now, and as much as I love a good bocadillo de jamon, I really could go for a decent Banh Mi. I know Madrid lacks a lot of international foods, but if there is anywhere that makes a Banh mi please help me out.
Vietnamese food is one of the things I miss the most and what I load up on most when I head back to the US for visits (or when I go to Paris). I've never found anything decent here--though I've been spoiled by living in places with big Vietnamese communities, so I'm pretty exacting... Same goes for Thai.
You'll have much better luck with Korean, Chinese, and Japanese.
Totally different cuisine, but I've had some good (and insanely cheap) sandwiches at Moroccan places.
