I had lunch today in this wonderful place right on South Street, a couple of blocks north of the Seaport. Found it serendipitously. Had a really good, nutty and hearty veggie burger on a crunchy wheat bun (the menu called it "sprouted wheat," whatever that means) with so-so roasted potatoes and a side of field greens. Coworker had a vegetable panini, which she also enjoyed. For desert we had good coffee and a shared a really juicy and fluffy almond cream cake that the waitress said was made on premises.
Aside from the really good food, what I really loved was the atmosphere. It's small and wood-paneled, really sunny with windows on two sides, one of which faces the East River and Manhattan Bridge. Felt a little hippie-San-Francisco, with people sipping coffee and working on their laptops. Completely incongruous with all the other food options in the area, which tend to either be corporate-stuffy or dingy hole-in-the-wall.
