Separated by an easy 5-10 minute stroll up ul. Freta, neighboring Stare Miasto and Nowe Miasto (Old and New Towns) can often merge seamlessly into one uncomplicated pub/restaurant experience. Both have streets lined with traditional, rebuilt Varsovian townhouses, although Old Town's have tended to stay a little truer to pre-WWII form. Either way, they each deliver that quintessential European ambiance that somehow manages to make kielbasa and beer taste even better.
As you'd expect, the area around Rynek Square in Old Town is your best bet for finding a high concentration of pubs, cafes and restaurants. During the summer months, multitudinous outdoor tables fill the streets, a refreshing change in a city not known for its evenly dispersed entertainment options. You may also want to check out ul. Freta to the north and ul. Swietojanska to the south, each with their own smattering of fun establishments. Overall, if you're looking to mix classic sight seeing with either a bite to eat or a few rounds to get your night kicked off, consider this the tourist-laden jackpot.
