Perhaps the Shotover Jet too? Glenorchy is a nice little escape from Q'town too. Joe's Cafe is a nice little breakfast place imho although a bit touristy/franchisey now. Fergburger is very popular if you like that sort of thing. Also, I highly recommend the Vknow which, again, imho is a hidden gem in Fernhill. I also enjoyed a trip on the SS Earnslaw which I never thought I would ever find myself typing or saying. If you do like golf then, aside from Millbrook, I loved Arrowtown Golf Course. The town itself is nice too with some really nice walks into the hills from it as well.
