Affordable, tasty, fresh South American street food. The menu actually has quite a few options considering how little their prep space is, and I've liked everything I've had from them so far.
The sandwiches are stuffed - the breads look small but they're filled to capacity and then some. They can be a little messy to eat (you'll need that fork, btw), and the last few bites will probably get soggy under all those delicious fillings.
The Arepas platter has everything except, ironically enough, an arepa. It's a decent amount of food, and one of the best deals you can get for that price downtown. Just writing this review is making me crave plantains.
Service is really friendly - sometimes a little slower than your average Subway or fast food place, but the guy who works there makes sure to pay attention to every customer and their order, so those extra two minutes are worth the wait.
Oh, and they serve churros!
