Treat yourself to something sweet today. In honor of its 30th anniversary, The Cheesecake Factory is offering slices of cheesecake today at the prices it charged when it first opened its doors in 1978: $1.50 per slice. The now ubiquitous chain started in Detroit with a small shop run by Oscar and Evelyn Overton. The couple later moved to Los Angeles where they expanded their business, eventually opening the first Cheesecake Factory restaurant in Beverly Hills in 1978. Today the menu boasts more 20 flavors of cheesecake including decadent options like chocolate Oreo mudslide and Dutch apple caramel streusel (as well as my personal favorite, dulce de leche caramel). With slices going for less than a cup of coffee or a gallon of gas, National Cheesecake Day just might be my new favorite holiday.
