I recently went to Roast for the first time, and I really liked it. The person who waited on me at the counter, who I think was the owner, was really nice and seemed really happy....which in turn put me in a good mood too!
This place is great because it totally doesn't have that franchisey Starbucks feel...you might really want to spend some time here reading, studying, or just people watching. I am sure you could sit there for awhile and noone would mind.
I was just in and out but I will definitely be back again soon.
