Ontario travel tips

Gourmets should visit the Market Broiler in Ontario

The Market Broiler at 4553 Mills Circle in Ontario offers you a cosy, casual atmosphere and good value for money. Even such fancy dishes as Crab-stuffed Salmon or Caramelized Salmon and Scallops will not make you bankrupt.

See the hand built wooden house in Ontario

Have a stroll around the magnificent Sam and Alfreda Maloof Foundation at 5131 Carnelian Street near Ontario. Maloof was a highly-respected furniture maker; his rocking chairs actually received recognition from several U.S. presidents. The house was hand built by him and his assistants. And do not miss the garden with native and Mediterranean plants.

Walk around the Ontario Convention Centre

If you are not interested in art, there is no need to enter the Ontario Convention Centre. But you need at least to walk near this place to feel the city vibes and meet locals. The area with a fancy white building surrounded by palms attracts locals. Then, go to Spires Restaurant and snack with the French toast.
