The Financial District's suits and secretaries flock to this prototypical, hard-drinking Irish bar for a minimalist good time.

The Scene
Tucked away on a side street near Downtown Crossing, this cheap, comfortable and decor-free watering hole is a local institution for thousands of area workers. During the week, a mixed crowd of Financial District personnel and Big Dig laborers settles in after quitting time, while the weekends draw 20-somethings and the occasional group of students. As for the service, anything beyond a brusque smile is a bonus.

The Draw
With lots of seating and a reasonably priced, well-stocked bar, J.J.'s caters to the drinker in all of us. A limited bar menu (simple chicken sandwiches and greasy fish-and-chips) is served until 9pm, but most patrons opt for a liquid dinner. The beer selection is exceptional; this is one of the few bars in the city that serves Labatt's Blue (a crisp Canadian lager) on tap.
