McDonald’s sales improved throughout the second quarter as markets reopened globally, but the fast food giant still faces a bumpy recovery.

Chicago-based McDonald’s said 96% of its 39,000 restaurants worldwide are now open, compared to 75% at the start of the second quarter. But the recovery is uneven. Improvement has slowed in China, but same-store sales are improving in the U.S.

McDonald’s net income fell 68% to $484 million during the second quarter. Earnings, adjusted for one-time items, were 66 cents per share.

That fell short of Wall Street’s forecast of 74 cents, according to analysts polled by FactSet. Revenue fell 30% to $3.76 billion, slightly ahead of analysts’ expectations.
