A friend and I are heading to Prague, Krakow, and Berlin over XMas and New Year's. She's a pescatarian, but is easy going about finding anything at any restaurant. We are both foodies not scared of going very local. My biggest concern is that we'll be in Prague over XMas. Usually when I'm travelling overseas over XMas I find a Chinese restaurant, as they are usually always open. But I've heard that Prague has a Vietnamese community, so I figured that might be a better option than Chinese food. Any suggestions (not just for Vietnamese food, but for all the cities we're heading to)? Also if you have any suggestions regarding New Year's in Berlin. I imgaine Brandenburg Gate is the obvious answer, but if there are more local activities, that would probably be better. Thanks!
