I’ve got a class tonight in Park Slope I need to finish some homework for. With all of central Brooklyn at my fingertips on this cool December night, where would be the best place to eat unforgettable, really cheap grub and break out my computer for an hour?

My options, considering I don’t want to spend more than $6:

Ba Xuyen: This place has the best Vietnamese sandwiches in the New York City, made even better by the iced coffees. I’ve been before a few times and I’m always in hog heaven. Total price of sandwich and coffee: $5.50.

Bake & Things: I hear the Trini “Doubles,” a couple of chickpea sandwiches covered in hot sauce and sitting in delicious bread, are to die for and they’re only five bucks, but there’s no indoor seating, so I’ll have to save this place for another time, when I’m in a rush.

Yun Nan Flavour Snack Shop: Ba Xuyen is perfect for when it’s warm out, and although it’s not cold, it could be nice to get some soup at a place I’ve never tried. The hot and sour soup here is supposed to be killer and there are pork dumplings too. But from reading the reviews on yelp, it seems this isn’t the healthiest choice (I don’t really want to taste the MSG). Ba Xuyen it is!
