Across the street from the Harvard Exit theater, in the space once occupied by the beloved Harvard Espresso, is the unfortunately named Joe Bar.
Why unfortunate? From my perspective, the name didn't exactly inspire me to go inside and since I resented the loss of the previous tenant, I grumbled when walking by and didn't try it out.
Anyway, I was wrong. the coffee is good and they have great crepes, both the Nutella and cream variety and the cheese and vegetable kind. There's not a lot of seating, so be prepared to eat the gooey deliciousness on the sidewalk outside.
Sorry I didn't come in sooner.
