"Our chips are hand-cut and come with a home-made aioli sauce with berbere spice and curry leaves," he said.

One of the best-value chips in Auckland can be found at popular seafood restaurant Swashbucklers, near Westhaven Marina. A huge bowl of fries will set diners back just $6.
Manager Mark Avery said the good-old fashioned hot chip was part of Kiwi culture and prices shouldn't be over the top for something that costs very little to make.
"The old saying cheap as chips means they should be cheap," he said. "We want to give our customers exactly what they want."
The Chip Group - an organisation made up of growers, chip manufacturers and oil suppliers - said prices for a serving of chips were on the rise.
For several years operators of restaurants and takeaway bars had soaked up rising production costs. But those costs were now being handed on to punters.
Other price rises were down to kitchens using better quality, but more expensive, cooking oils.
