Magnolia bakery on Columbus Ave at 69th st. has outdone itself in preparation for Valentine’s Day.   The store is beautifully decorated with pink curtains, hanging hearts, pink cupcakes and more.   I’ve attached photos but check it out in person to get the full flavor.  While you’re there, try one of the pink, Barbie cupcakes (or if you’re there in the morning, stick with my favorite Apple Cranberry Walnut muffin).
