Totally comfortable with it - any specific places you'd recommend?
I haven't ventured to that area before/after games. I'm usually in and out on the train, so if I stop anywhere, it's somewhere like Edison right near the arena.
Fornos and Iberia are literally massive, the nearest to Penn Station, and probably the most popular amongst the locals, though not my personal favorites.
Mampou Tapas is the shit, has a solid bar, and is maybe 1 block over from the aforementioned.
Sabor Unido is excellent (especially for the price) and just another block down.
If you're just looking for a bar with pretty standard food Sagres is where it's at.
Ferry St bbq has good Brazilian bbq, but I'm not sure what their indoor policy is and they don't have an outdoor setup.
If you're looking for the best Portuguese pastries I've had outside of Lisbon or Sao Paulo Pao da Terra is amazing. Their chorizo stuffed bread and pastel de nata is to die for.
I'm sure you can Google all of their menus.
Regardless, if you haven't been over that way it's definitely worth it and not a trek from the Rock nor Penn Station.
