Seven Grams is a great place to not only get a great cup of latte, but, well, a lot of other things too. They have a great selection of baked goods, sandwiches and soup of the day.
When it first opened it was easy to get a spot and sit there to enjoy your coffee for a while, but now, with its great location (tucked away but accessible from the Yorkville residential area), good luck finding a spot. If you can, enjoy!
It would still not stop me from going back. Great place!
