Where to eat the best Trüflü Parmesanlı Burger in Turkey?

The bread is very nice, soft and enjoyable to eat, and it smells of butter. However, I think the smash patty trend should end. I can't taste the meat. When I take it out and eat the hamburger patty, it tastes good, but there's no noticeable difference in taste inside the hamburger. Moreover, it dries out during the eating process.
