Margate for me... I had a gran near there and visited her all thru childhood and until she died. Great fish and chip shop, a bit of a walk with a 'special' bag to carry home booty... then there was the polystyrene box that fitted a block of icecream for Sunday treat. She had no fridge until 1970's. So icecream in its box was put in cellar til needed. Milk was kept in pail of water at back door. Another treat was to go to nearby pub and get a bottle of perry, I presume non alcoholic!
We lived in Ireland then so there were all the great sweets not available at home such as spangles, maltesers, mars bars, topics etc.
Margate had a place called Dreamland for big dipper etc and the seafront lined with cafes ... ah yes candy floss, knickerbockerglories
