We tried Korzo this weekend. (Used to be "Eurotrip" -- I'm glad they ditched the old name.) Apparently there's new management, but the menu is basically the same Central/Eastern European mixture -- Czech, Hungarian, German, Austrian, Polish. Some of the dishes are "old school," and some are sort of updated versions. Everything we tried was great, especially the langos (Hungarian fried bread). Nice variety of imported beers too. Wish I had enough room to try the grilaz dessert! Overall, definitely worth checking out.
667 5th Ave., between 19th and 20th
P.S. As of last week, it's open for weekday lunches too.
