Everything on a Waffle by Polly Horvath

From chapters.ca:
Readers will know right from the start that the narrator of Everything on a Waffle is going to tell her story straight and pull no punches. Primrose''s parents have been lost at sea, but she believes without an iota of doubt that they are still alive, somewhere. She moves in with her Uncle Jack, but feels generally friendless. Her only real refuge is a local restaurant called The Girl on the Red Swing, where the owner, Miss Bowzer, serves everything on waffles -- except advice and good sense, which come free of charge and are always reliable.
