Best doner I had in germany was in Coburg. Methuselah's uncle pushed this little cart around and cut them off a cone of what looked like home-stacked mystery meat, pretty sure some mutton in there. He put them in 1/4 of a home-made flat bread that his mother made for him each day, split open for the pita effect, which were about the size of a dinner plate. Had to be about 2 pounds when it was all done, and he liked us so ours were usually bigger. Simple yogurt sauce shredded cuke/onion/tomato on top, the meat spiced perfectly, just the right mix of fatty lean and gamy (not too much of any, the right amount of all 3). Wow I could eat one of those for every meal. When he ran out he went home, and he ran out fast. There was always a line even though he always seemed to be in a different spot, people found him. Luckily he liked us so we always had one even if he closed and waited for us (yeah I actually lost weight on my mission, go figure).
One of the better gyros in Utah is actually at Crown Burger. Pretty standard tzitziki sauce and tomato/onion. But the meat is always good and the pita is warm, and the fixings fresh. For gyros that is my go-to spot in Utah. Plus their onion rings and fry sauce are the bomb.
