Riverdale Perk is a great morning stop for coffee and a bite. Don't let the sea of strollers scare you away - there are usually a few seats outside you can escape to that are tranquil and serene.
The lattes are deep and frothy, and the bagels are lightly toasted with just the right amount of cream cheese.
The staff is also extremely friendly and courteous. If you ask for water, they'll bring you a carafe w/ cranberries floating on top. It doesn't get much classier than that!
