Johnny Rockets Braintree - Kids Eat Free (?)

Reader, Lynne from Weymouth, is reporting that you can score free kids meals at Johnny Rockets at the South Shore Plaza in Braintree.  When?  Mondays-Thursdays from 4pm-9pm.  You only get a free kids meal with the purchase of an adult meal. 

I have no idea about dates this is valid until and cannot find anything out about it with Google searches.  If you know anything about this promo, feel free to comment and I will edit accordingly!

Thanks Lynne!
