Good fish and chips starts with fresh fish, a light batter that stays crisp and chips fried hot so they are not greasy. Busy shops turn their oil and stock over quickly, which tends to mean fresher food. Eat it soon after it is cooked, since steam softens the batter in a closed wrapper, and ask for salt and vinegar to be added at the counter rather than before. In a popular tourist spot, queues build at lunch and just after sunset, so go a little before or after the peak. A takeaway meal by the water is a simple pleasure, but dress for the wind.
For a hot lunch or dinner by Lake Tekapo, The Better Batter is a very well-rated stop on Lakeside Drive.
