A staple of late-night dining in the Hub, the South Street Diner (178 Kneeland St., 617-350-0028, southstreetdiner.com) has been a local fixture in one form or another since 1947. Thanks to an annual tradition, however, non-night owls can enjoy all this classic eatery has to offer and more at the free South Street Diner Block Party. This family-friendly fest taking place September 16 from 2–6 p.m. between Kneeland and Beach streets features pony rides, face painting, cartoonists, an ice cream stand, a live DJ and even one of the area’s latest entertainment sensations, Archery Games Boston, which hosts an area for its foam-tipped bow-and-arrow combat contests. And did we mention the free hot dogs, hamburgers and other refreshments that are available? Who says you can’t have a good time and still get to bed early?
