Boston Pizza invites you to their dining room. They are open after-hours from Friday to Saturday. Check in periodically for promotions and special offers.
Boston Pizza is universally a good place to take the kids, and is pretty consistent but I have to say I was impressed with the Drumheller location's service (visited as a group, 4 adults and 5 kids = chaos!!) and they were the best! Made it easy for parents to have a relaxing meal out with the kids and still ensure everyone has a good time!
