When we visit Auckland overnight, we choose the Heritage Hotel in Wyndham St largely because of the vegan menu at Hectors Restaurant. Although it does have a general menu that includes meat, the vegan menu is separate from it and cooked in a separate kitchen. The lunch specials are interesting - a starter, a main and a dessert delivered on a tray. There a choice of three or four such vegan meals. Because of the two menus, Hector's is a food place to rendezvous with both vegan and non vegan friends. It has a comprehensive wine list and good coffee.
For those staying in this hotel, the breakfast buffet is amazing. As well as a broad international buffet selection, it includes a stunning raw food vegan buffet and diners can have the run of all options. My husband is vegan and I am vegetarian, so this allows me my scrambled eggs if I want them, as well as such vegan delicacies as coconut yoghurt.
The hotel itself is four star and very environmentally savvy in its practices.
