This small spot in East Arlington has arguably one of the best iced coffees in the Greater Boston area.  The iced coffee lacks the acidic aftertaste many other iced coffees have and has a pleasantly smooth and balanced taste.  Although the espresso drinks are mediocre, the brewed coffee is delicious.  The favorites are the Dancing Goats and Quebrada House brews, although there are many other great options to choose from.  To go with the coffee, Quebrada is a bakery that has tasty scones, croissants, and muffins.  There is not much seating, but the regulars know to get there early for their spots.  Expect long lines on holidays, but quick service.
