To call it a "brewpub" would be a bit of an exaggeration, since all they serve are empanadas from El Porteño. Which, don't get me wrong, are quite tasty! They have 7 taps, which on a recent visit serve one of their own beers, as wells a fridge with about 100 craft brews. I had the St Bernardus Prior 8 Belgian dubbel (delicious), while Dr. P had a Bockor Jacobin Rouge sour (very delicious).
So, while I can't really recommend it as a place with a full menu, they have some tasty beers on tap (and in the fridge), and tasty empanadas for them to wash down. As a place for a quick snack or to pick up some good beers near Dolores Park (or, as Dr. P. tells me, for an impromptu date), it's a great little spot.
Social Kitchen Waterside Porter
While I've got your attention, lemme throw in a review of another Social Kitchen beer, their Waterside Porter. I generally like porters, but a lot of west coast brewers, being hop heads, tend to overtop them, and unfortunately, the tannins in the dark grains that give porters their color and flavor don't play well with hops.
This one, however, is done right. Presumably, they're using carafa malt, which is a dark malt that does play well with hops. It's well-balanced, with good mouthfeel, and not too strong. A very well-done "west coast" porter.
Social Kitchen Waterside Porter, 5.9% ABV, 33 IBU.
