Burger King has revealed a 13% fall in its third quarter profits to $41m on the back of a 3.7% slump in like-for-like sales. Revenue dipped 1% to $596.9 million from $599.9 million. The company has guided to a better than -3.7% like-for-like sales for Q4 as it said March momentum will feed through to current trading. US trading was hit by an 8,2% fall in like-for-like sales in January due to poor weather. The Miami company is expanding its menu with items that appeal to both budget-conscious customers and those willing to spend more. The burger chain continued to push its $1 quarter-pound double cheeseburger during the quarter but also launched the pricier Steakhouse XT burger line in February, which executives said helped bring in customers. It's also planning to add a BK Breakfast Muffin and Buck Double cheeseburger and add the more expensive BK Breakfast Bowl and BK Fire-Grilled Ribs in the current quarter.
