McDonalds shares hit record highs on Wednesday, after upmarket burgers and $1 drinks boosted sales.

The fast food chain recorded its highest quarterly sales at established stores in five years in the three months to the end of June, with turnaround efforts and the use of better ingredients paying off.

UK stores recorded their highest sales ever, with sales at stores open at least 13 months jumping 6.6 percent from this time last year.

McDonalds reported earnings of $1.70 per share on $6.05 billion in revenue, higher than the $1.62 per share on $5.96 billion in revenue expected by analysts.

“We’re building a better McDonald’s and more customers are noticing,” said Steve Easterbrook, the company’s chief executive.

“Our relentless commitment to running great restaurants and keeping the customer at the center of everything we do is generating broad-based strength and momentum across our entire business.”
