"Fruits" is right across the road from the best snorkelling area on Raro and they also do a a really good fish & chips. For NZD$10, the serving is huge - the fish is really fresh and the chips crispy on the outside and fluffy on the inside. Definitely worth a visit for lunch after a snorkelling session.
The service is friendly, but can be quite slow (especially if there are groups there) as there is usually only one person working. The fruit smoothies are also highly recommended!
