Best meal I ever had was in a long gone, tiny French restaurant in Whippany, New Jersey (US), called 'La Delice'. It was a Filet of Wild Pacific Salmon with winter vegetables and Spinach seasoned with herbs and bacon. Outstanding!
Another memorable dish happened some years ago, just outside of Zurich, Switzerland where H and I stopped for lunch (pre fix?). The special was a generous platter of sausage and potatoes smothered in beer gravy......accompanied by a huge mug of ale on tap, of course!
Best dessert I ever had was in a genuine (converted) castle in Burgos, Spain; I ordered the 'Oef's a la Niege' (Floating Islands). Snowy Meringues over warm custard encased in a freshly baked puff pastry cup and the entire thing drizzled with Caramelized sugar!
......Heaven!
