So right off the bat I'm willing to admit I didn't know what an arepa OR pupusa were before entering the doors of this fine establishment.
To sum it up for you, arepas are magical and pupusas are their bewitching brother in law. We tried an arepa with fries and my god, the corn like sandwich filled with meat, cheese, and veggies was so delicious. I would say it was like the Colombian/Salvadorian version of an overflowing cheese steak. As for the pupusa, if you stuff anything in anything you're pretty much set up for delicious success. I don't care how that sounds, but I stand by it.
The dining room was small and plain; it was perfect. Can't wait to return.
