• Through Jan. 29, Burger King is giving away a free small cup of coffee with the purchase of a breakfast sandwich.

• At Pizza Hut, any medium or large pizza ordered online is 50% off through Jan. 10 — its best-ever online deal, says Carrie Walsh, chief marketing officer.

• IHOP, through Feb. 9, is bringing back “All You Can Eat” pancakes. Customers who order combos with eggs, hash browns and sausage, bacon or ham can keep requesting pancakes. “As long as you can keep eating them, we’ll keep serving them,” says Natalia Franco, senior vice president of marketing.
