A piano bar that has been open since Prohibition ended, Charlie Brown's has hosted all sorts of colorful characters over the years. While you can't go wrong bellying up to the bar, it's the expansive patio that beckons those who are driven to scrawl prose into worn notebooks or type furiously in the glow of a laptop screen. Cigar and cigarette smoke wafts through the air, drinks are cheap, service is fast and friendly, and there are plenty of outlets to keep all your technology charged while you sip away afternoons that turn seamlessly into evenings at the longstanding landmark.
