LAKEWOOD, COLO. — Earnings at Einstein Noah Restaurant Group, Inc. dipped 13% in the second quarter, while revenues rose 0.2%. Net income in the period ended June 28 was $3,080,000, equal to 18c per share on the common stock, down from $3,556,000, or 22c per share, in the second quarter of fiscal 2010. Revenues rose narrowly to $103,677,000 from $103,473,000.
