Frosty Moons is an ice cream shop at 38 Drews Avenue in Whanganui Central, with a 4.4 rating from 99 Google reviews. Good ice cream shops live and die by the churn: those making small batches on site tend to rotate flavours with the seasons, and the most popular ones can run out by late afternoon, so regulars arrive early and ask what's fresh. It pays to ask for a taste before committing — a confident shop will hand one over without fuss. Sorbets are another quiet test, since real fruit with no cream leaves nowhere to hide. Set on Drews Avenue in Whanganui's riverside old town, Frosty Moons is well placed for a cone after a walk along the water.
