Noodles & Company (NASDAQ:NDLS) saw shares fall today after the company reported earnings, missing expectations on both profit and revenue. The stock shot up 70% on its first day of trading last summer, when it IPO'd amid enthusiasm over stocks in the fast-casual dining space, but now the company may be falling back down to reality.

In this video from Thursday's Investor Beat, host Chris Hill and Motley Fool analyst David Hanson discuss Noodles & Company, and the fast-casual space. David says the business of fast casual just isn't as easy as the market thinks it is. Noodles & Company isn't founder-run like some of the other extremely successful businesses in this space, and is valued at a shocking 70 times next year's earnings. To David, this company lacks the same prospects as a Panera Bread (NASDAQ:PNRA) or a Chipotle Mexican Grill (NYSE:CMG), and the valuation is far too overenthusiastic.
