September is “National Breakfast Month,” so what better way for South Street Diner to celebrate than by hosting its annual customer appreciation day on Sunday, September 14, 2014 from 2 p.m. to 6 p.m. The day will feature free pony rides up and down South Street between Beach and Kneeland Street, along with cartoonists, face painters, an ice cream truck and a live DJ spinning family-friendly hits all afternoon. South Street Diner Owner Sol Sidell will be on hand to meet and greet his loyal customer base and serve up hamburgers, hotdogs and refreshments inside his establishment that will be free for all ages in addition to all of the day’s free activities.
