Gopals Dairy is a corner dairy on Main South Road in Hornby, Christchurch, with a 3.8 Google rating from the locals who use it for the quick top-up shop. A good dairy earns its place in a neighbourhood by being there when the supermarkets aren't worth the trip — a litre of milk, a loaf of bread, an after-school ice block or a hot pie from the warmer. Regulars tend to judge one on the essentials: how fresh the milk is, whether the chillers are properly cold, and if the prices on the small things are fair. It also pays to check whether a dairy takes EFTPOS on small purchases and what time it actually shuts, since those two details decide how useful it is day to day. For Hornby residents along Main South Road, having a dairy like Gopals within walking distance is exactly the convenience the trade exists for.
