Pántlika is an easy-going outdoor bar tucked away on the far end of Budapest's City Park. If you need a break from the nearby tourist attractions — Heroes Square, Vajdahunyad Castle, Széchenyi Thermal Bath — you can refuel here with a cold beer and snacks. Pántlika offers a truly local experience as most tourists don't come all the way to this side of the park. Note that they're open only during the outdoor season (usually from April to mid-October).
Interestingly, Pántlika's quirky modern building used to be an information desk during the annual international expo, which took place in the City Park until 1973 during communist Hungary; the curvilinear five-pointed aluminum roof resembles a red star, an obvious hat-tip to the ruling regime.
