NEW YORK - According to the latest NRN-MillerPulse survey, restaurant same-store sales and traffic increased in June, with QSRs maintaining their momentum and casual dining rebounding sharply after a weak May, Nation??s Restaurant News reports.

Overall, industry same-store sales increased 3.2% in June over the same period last year, with sales at QSRs up 3.9%. Full-service restaurants, which include casual-dining brands, recorded 2.2% growth.

The survey also revealed that while traffic increased at both QSRs and full-service restaurants in June (1.9% and 0.1%, respectively), they remained down from earlier parts of the year.

Operators expressed optimism that sales will continue to improve in July, with 65% of operators surveyed predicting same-store sales will increase. Meanwhile, operators from fast casual, casual dining and fine dining said they thought things would improve over the next six months, while operators from the QSR segment said they thought things would get worse.

"I think we are going to see more of the same: Volatility. Uncertainty. A continuation of industry same-store sales in the 2% to 3% range," said Larry Miller, creator of the monthly MillerPulse surveys. "We're hopeful that as we pass these domestic hurdles ?" elections and the fiscal cliff ?" things will accelerate into calendar 2013."
