Beef-a-roo finally reveals why we are so crazy for their cheddar fries.

Beef-a-roo is a Rockford staple. With seven locations and millions of buckets of cheddar fries, the Rockford chain is celebrating its 51st year in business.

When we started Ate One Five, we knew we had to make a stop at Beef-a-roo.

So we did. And now we know the secret behind their epic cheddar fries.

While you might think the secret is the salt (which is amazing by the way), we think the secret is in the sauce.

You can get the deets on that secret at the 1:50 minute mark in the latest Ate One Five episode.
