Found the cafe to be a bit overpriced - but if the profits are going back into the gardens, I don't mind the spend. The coffee here is really good and they have a fully stocked tip top fridge. The views are lovely from the deck!
While it's more expensive than your standard cafe, the views are gorgeous from the deck. If you're only buying ice-cream or a cold drink, you can avoid the long queue by going to the eftpos man in the centre.
