Restaraunt Markus

Restaraunt Markus in Old Town is famous for its stakes, the best ones in town, people say :)

Nan Bei

Nan Bei for me sounds like copy to Gan Bei (popular Latvian Sushi place), but I don't see any logic here as in case with Kabuki/Labuki.
Update: Chinese Nan Bei restaurant in Vilnius is not related anyhow with Japanese Restaurant Gan Bei in Riga. On top of that, the service and prices here could be much better.

Labuki

Lithuania + Kabuki = Labuki. A famous and one of the best Sushi bars in Baltic States.
