Surprising stay in Riga. I heard about this town a few months ago, and it is now one of my favorite destination. The atmosphere during the WE is just amazing, great if you like to party (be just a little bit careful to avoid problems). We stayed 3 days there, too short to see everything, taste all the local food and beers. Two countries in one (Russia and Latvia) which makes the destination even more interresting.
Insider Tip:Go to the russian area next to the bus station, and visit the markets. Very good bargain there, even if a bit of russian language may help. (Not very safe during the night). On sunday, many people goes to the "vasingtona laucuns" area to have a beer, and watch the alternative art exhibitions.
