The burgers at http://www.fergburger.com/ are very good, especially the 'Big Al':
"Al delivers a double serving of prime New Zealand beef (1/2lb), lashings of bacon, a whole lotta cheese, 2 eggs, beetroot, lettuce, tomato, red onion, relish & a big wad of aioli"
As you can see by the many posts lately, I'm posting from regular computer instead of my phone. I've just finished the 2-week tour of New Zealand and tomorrow I fly up to Christchurch and then on to Tasmania.
