Prague, Czech Republic
Extremely popular among students, this tiny Old Town pub (near the Staromestka Metro station) is generally pretty crowded, day or night. Reserve a table in advance or try to wedge your way in at the bar until you can snatch one up as it empties. During the day, you'll find local students and ex-pats (and, sometimes, their professors) having a quick lunch or enjoying interesting conversation over a cup of coffee or a pint of beer. In the evening, crowds are a bit more raucous, what with the live music and well-priced cocktails. A visit to Hany Bany is definitely worth enduring the cramped quarters.
