@nbcchicago: McDonald's is getting a new breakfast biscuit -- but it's only for a limited time. Starting Tuesday, the Chicago-based chain's new Honey Brown Butter Egg, Cheese & Bacon Biscuit will hit menus at participating restaurants. "This breakfast sandwich is the perfect spin on the classic bacon egg and cheese, taking those ingredients and nestling them between two freshly baked biscuits with creamy, toasty Honey Brown Butter," McDonald's said. It's not clear how long the biscuit would be on breakfast menus, but it debuts July 21.
