Softer sales trends in January among quick-service restaurants appear to indicate a more lingering weakness, even after adjusting for the impact of bad weather, according to the most recent NRN-MillerPulse survey.

The quick-service segment overall has held up well over the past three years and continued to outperform casual dining in January. Fast-food restaurants recorded a same-store sales increase of 1.6 percent, while both fast-casual and casual-dining restaurants recorded a decline of 0.9 percent, respectively. Industrywide, same-store sales were flat for the month.

On a two-year basis, however, quick-service sales rose only 2.2 percent, the weakest results since July 2011, the report found.
