What it's known for
Threes' flagship brewpub, open since 2014: a big bar with house beers poured from serving tanks (lagers are the strength), guest beers, wine and cocktails, a large gravel backyard and food from Grand Army. Open noon to midnight Monday to Saturday and noon to 11pm Sunday.
Between 3rd and 4th Avenues; Union St (R) or Atlantic Av-Barclays Ctr. No outside food (desserts excepted), and dogs only at the sidewalk seats. It's open latest on this route, so finish here.
Check opening hours with the venue before you go: they change, especially early in the week.
