Day Trip in Providence Reqs

I'm flying in for a work trip and am looking for a coffee shop req that is chill enough I can do some laptop work for a few hours. Afterwards I wouldn't mind exploring the neighborhood without having to move my car. I've heard federal hill is nice. Any good coffee spots/lunch spots/happy hour spots/things to see around federal hill? Should I focus on another neighborhood? I'm a fan of walking historic neighborhoods and checking out the restaurants and dive bars the locals typically haunt.
