Cora's is a good spot for breakfast. There isn't much around the Harbour Castle area for dining. You would be better off taking the subway up the Dundas Station and eat at the The Senator Diner for either breakfast or dinner, the prices are resealable. There is lots of dining in the area as well, Another fave of mine that isn't overly expensive is Quinn's Steakhouse & Irish Bar at the Sheraton Hotel, Also near by if you like old school Italian cuisine there is Little Anthony's Italian Ristorante. Another option that' isn't far from the Harbour Castle is the Library Bar at the Royal York Hotel. Great food and great atmosphere, Also worth checking out is O&B Cafe Grill at Yonge & Front st, they sever Lunch and Dinner and on weekends they serve à la carte brunch.
