Vilnius's craft beer scene grew rapidly after independence and there are now several bars in the old town area where you can drink well. Craft Pub on Stiklių Street is one of the more popular, with a long list of Lithuanian craft beers on tap alongside imports from Latvia, Estonia, and beyond. The space is compact and tends to fill up on weekend evenings, but the beer selection is genuinely interesting.
Good Lithuanian craft breweries to look for include Sakiškių, Apynys, and Dundulis. Lithuanian dark bread beer (gira/kvass) is also worth trying as a non-alcoholic or low-alcohol option — it's made from fermented rye bread and tastes nothing like what most people expect.
