Pusateri's is proud to have been sourcing Beef locally grown in Ontario. Dry-aged for a minimum of 21 days and Naturally marbled, The Rib Steak Bone In is very juicy and flavourful. Look forward to that great Steakhouse Experience, when cooked just right. Medium rare: Cook until internal temperature is 145°F for 15 seconds. Medium: Cook until internal temperature is 160°F for 15 seconds. Well done: Cook until internal temperature is 170°F for 15 seconds.
