National Prime Rib Day falls on Wednesday, April 27. But why celebrate that delectable hunk of beef for one day when you could celebrate it for five? III Forks, North Texas’ most iconic steakhouse, will offer a Certified Angus Beef Prime Rib for $54 from Wednesday, April 27 through Sunday, May 1. Prime rib is not on the restaurant’s regular dinner menu, so don’t miss out on this rare opportunity!
