and if those count, then the best shawarma (no frills, handmade pita, perfectly marinated and grilled meat, a little garlic sauce... oof I dream of this) was at Mama Noura's, Riyadh-KSA. The best veg shawarma (cauliflower or eggplant wrapped in pita) so far was at Al Comodor Falafil, Sharjah, and they also do the best falafels in the UAE (I've had enough to know).
The best frankie wrap (stir fried meat with onions and tons of spices, wrapped in paratha) I've had was a little hole-in-the-wall, at a historical market street in Kolkata. In Taiwan, I'm still looking for my perfect wrap!
