The Bay Area McDonald’s have tinkered with the company’s legendary French fries only once before — when they introduced Gilroy Garlic Fries a couple of years ago.

Today, Nov. 7, a new version will be introduced at all restaurants in NorCal and Hawaii.

Cheesy Bacon Fries, “smothered with real cheddar cheese sauce and smoky bacon bits,” will be available for a limited time only, from now until the end of the year, the company announced.
