Concierge.com's insider take:
El Quinto Pino may be New York's most authentic tapas bar, as frenetic and cramped as the best spots in Madrid. An offshoot of the larger Tía Pol, this sliver of a restaurant offers few surfaces to dine on (just a bar-top and ledges) and even fewer places to sit. Still, the small plates of fried, grilled, and marinated morsels are hard to resist, particularly after a few glasses of chilled Txakoli (an effervescent Basque vintage from the all-Spanish wine list). You'll come for a snack but end up staying for dinner. Share crisp salt-cod beignets, anchovy fillets, and the irresistible signature sea urchin panino. Though there are no sweets scribbled onto the menu above the bar, insiders know to request the unadvertised casadielles, delicious fried ravioli with walnuts and honey.
Open Sundays through Thursdays 5 pm to midnight, Fridays and Saturdays 5 pm to 1 am.
