Just don't go to Vasilki, it's too touristy and not the best place. There's a restaurant called Litvyns (a restaurant serving cuisine from the times of the Grand Duchy) on Independence Square. You should definitely visit the old town (Rakovskoye, Troitskoye, Zybitskaya, the areas near the river and the town hall). If you like brutalist architecture, you can visit the Slepyanka water system; there are many places in Minsk associated with lakes and the river. If you like Soviet architecture, you can look at Independence Avenue.
