Today (June 30) is National Cheesecake Day, and as in previous years, the Cheesecake Factory is offering half off any slice of cheesecake — including the Oreo Dream Dream Extreme cheesecake, which debuted today — when you dine in.

However, if you sign up for this Facebook offer, you’ll have an extra day, tomorrow (July 31), to take advantage of the deal, in case you want to avoid the crowds.

Of course, if you’re a die-hard cheesecake fan, you can sign up for the Facebook offer and go both days!

The Cheesecake Factory has locations in the Inland Empire in Rancho Cucamonga, Riverside, Rancho Mirage.
