Everything pales before the seasonal flavors. Apple Cobbler, Spiced Pumpkin Pie, Iced Gingerbread...drool...
Carrot Cake and Lemon Poppyseed for the "regular" flavors.
Key Lime and Lemon Zest Luna bars are good if you don't mind them melting in your pocket. And Dulce de Leche Luna bar is better than a candy bar!
