This small coffee shop in East Cambridge serves great coffee and, perhaps more importantly, excellent made-from-scratch Liege waffles (a brioche-type waffle with lumps of sugar). There are special waffle flavors on weekends as well, like honey jasmine and corn jalapeño cheddar. If you can snag a seat, this could be a good place to do work, but be aware that this place closes at 2pm during the week.
