Well I think I had the best gelato I have ever eaten at the Waiheke gelato place. The chocolate sundae with chocolate sauce was $12, but so worth it. Ended up having two over the weekend they were so good.
Avoid the Red Crab Thai resteraunt. Worst service I have had in a very long time, lied about running out of ingredients for drinks before aditting they were just too busy, tried to overcharge us(ALWAYS check your bill) and in general ruined what could have been a nice evening with very rude waiting and serving staff (except the water girl who was attentive and friendly).
At least the Gelato place just below it was awesome salvaging the evening!
