Scarborough Fare is listed as a playground, but its description is of a cafe: an airy indoor and outdoor spot on the water at 147 Esplanade, Clock Tower End, Sumner, Christchurch, serving casual, globally inspired food for breakfast and lunch. It is rated 4.5 on Google from 1143 reviews. Check with the cafe before planning a visit around children's play.
A cafe beside a beach suits a relaxed outing, and the best seats go early. Weekend mornings and sunny days are the busiest times in a seaside suburb, so arrive before the rush or be ready to wait. If you are bringing children, ask whether the outdoor tables are sheltered, since a breeze off the water can be strong. Check the menu for dishes that suit your group, and ask staff about dietary needs before you order.
For breakfast or lunch by the water in Sumner, Scarborough Fare is a well-reviewed place to stop.
