Depends a bit on what you call 'pancakes'. We always used to make thin pancakes or 'crepes' but in the USA and Canada they seem to favour thicker ones (like 'Scotch' pancakes) where you can add items to the batter before frying it.
Years ago we both worked in Holborn and used to go to a pancake house called My Old Dutch after work now and again. Anyone else remember it? Don't know if it's still there. All sorts of savoury and sweet pancakes 😋
I will shortly be making my pancakes. I make my own but I do see mixes and bottles in supermarkets. Husband eats whatever I give him. 🤣. Daughter is the same.
My favourite filling is chopped banana with whipped cream on top. My son just likes lemon, sugar and sometimes some maple syrup.
