CNN -- Starting Tuesday McDonald's will be changing its late night menu.
Signature Crafted Recipes, Artisan Grilled Chicken Sandwiches, Buttermilk Crispy Chicken Sandwiches, Buttermilk Crispy Tenders, Filet-O-Fish and premium salads will not be available from midnight to 5 a.m., according to the restaurant chain.
Other late-night menu items, including Big Macs, Quarter Pounders and McNuggets, will still be available.
"We'll be simplifying what's served after midnight so customers can get the most popular favorites," said Andrea Abate, spokesperson for McDonald's.
McDonald's wants to reduce the "complexity" of menus and store operations, CFO Kevin Ozan told analysts at a conference last month.
Meanwhile, the company is expanding its breakfast menu — an important meal for fast food chains.
In February McDonald's introduced Donut Sticks .
The new item is only available during breakfast hours, though the company serves other breakfast items all day.
