I had been recommended this place by a friend who had stumbled upon Kaffe 1668 and was pleasantly surprised. I walked in around 10:30 am and got the strange feeling that I was in a New York Club but I kind of liked it. However, the next time I went back, I almost thought I had lost my mind because it was Kaffe 1668 on Greenwich St. but it looked completely different! Not to be too confusing, there are actually 2 locations of Kaffe 1668, both on Greenwich St. in TriBeCa. Kaffe 1668 serves a decent shot of Black Cat Espresso by Intelligentsia in very beautiful cups in a great atmosphere with (I suppose) good food. The selection of juices and breakfast and lunch items was great at the location further north on Greenwich St. but was much more limited at the other location. The vibe is really unlike any coffee shop I've been to before. Very dim lighting in a long, dark, hallway with nice wooden tables and mason-jar lamps. The espresso at the further north location (see? this is so confusing!) was a much more flavorful, fruitier pull than the other. The south location is much smaller, has a very creative seating arrangement (picnic tables, etc.), and didn't have much food. Overall, great vibe, friendly people, and pretty good (most of the time) espresso.
