Pizzerias bid customers a 'hearty' Valentine's ... 'er Galentine's ... Singles Awareness Day The typical restaurant business marathon known as Valentine's Day is about to hit, but this year studies are showing pizzeria operators that many of their customers will also be celebrating being straight-up single, or just having some great female pals.

(Provided) If restaurateurs are romantics at heart, pizza restaurateurs have got to be the proverbial "Don Juans" of the industry. For proof, look no further than any restaurant industry reporter's email inbox in the run-up to Valentine's Day, where you will find a deluge of urgent notices asserting the values of one pizza brand's heart-shaped pies over all the others.
