Every time I go to this pupuseria, I feel like I have a rock in my stomach for hours afterward. That's because I gorge myself on delicious cheese pouches & you should too.
Hot tips: get the zucchini AND herb (you can combine pupusa fillings). Bring friends who speak Spanish if possible but do not get offended when they ask your friends what "La Americana" wants. Just embrace it. Servers might try to talk you out of things they think you can't handle, like El Salvadoran horchata (nuttier and coarser than its Mexican counterpart). Know thyself.
Great place to pick up take out dinner for a group or family.
