Now that this thread is alive again, my biased vote goes to the Samurai Pork Burger in Thai McD's. Anyone concur?
I had a Kiwiburger down in Christchuch last December. I tried unsuccessfully to flush it from memory... it was a standard burger with egg and something that looked like a slice of beet! However, the most attractive local Christchurch fast food joint was a BK that all decked out in U.S. retro (1920's - '60s); classy job.
