A rise in the price of ingredients has prompted price hikes at fast-food restaurants.
A rise in the cost of ingredients has prompted price hikes at fast-food restaurants.
The popular double-double at In-N-Out has increased 15 cents since last month.
Hamburgers and cheeseburgers went up 10 cents each and drinks increased 5 cents, the chain told NBC Bay Area. French fry prices were unchanged.
"We make every effort to keep our menu prices as low as possible," In-N-Out EVP of Planning and Development Carl Van Fleet said in a statement. "Unfortunately, we have seen some pretty significant cost increases over the last year and we had to take a small price increase in order to maintain our quality standards."
Overall food prices have jumped nearly 3 percent since April, which is the highest increase in more than three years, officials said.
Other popular fast-food chains like Chipotle have also been adjusting prices.
