Casual-dining chain BJ's Restaurants (NASDAQ: BJRI) said it would open just four to six restaurants next year, down from 17 last year, as the company reported its sixth straight quarter of declining comparable sales. Labor costs are rising, mall traffic is falling, and food deflation had made prices lower at supermarkets; but the biggest problem for the industry appears to be oversaturation. McDonald's (NYSE: MCD) shares have surged nearly 40% this year as new CEO Steve Easterbrook revamped the Golden Arches with moves like all-day breakfast, better value deals, and refranchising company-owned locations.
