I first discovered El Quinto Pino while on a date a couple years back. Since then, it has become a go-to place for casual drinks and great tapas with friends. Though not very spacious (or inexpensive), El Quinto makes up for it with delicious small plates and a nice selection of Spanish wines.
Attentive and approachable, the staff is well-versed on their menu. The last time I visited, I received a bar-side lesson on Jerez (Sherry). Our waitress/bartender even conducted a small tasting for my companion and me. Tip: show up a little early for happy hour in order to get a seat.
