I would find Taybarns difficult, although there is a great buffet range, there is also a huge cake/dessert section. As it's pay once and eat as much as you like, I don't think I'd be able to resist the sweets.

I am eating quite a lot of Indian food, it's often made with a fair bit of cream and Ghee (clarified butter) I have a curry and a veg bhaji of some kind, and just miss out rice and breads.
