On CAPS, 66% of the 510 members who have rated OpenTable believe the stock will underperform the S&P 500 going forward. These bears include iamvoltron and showmethefacts.

Just last month, iamvoltron noted that the OpenTable bear case all boiled down to price:

[OpenTable] at 2 billion is overvalued, the room is still open for competition. As others suggested, social networks rating the restaurants might be more useful (all sort of mobile phone apps rating restaurants near you). These can undercut [OpenTable] in pricing and not charge per reservation.

In fact, OpenTable sports a particularly lofty P/E of 149. That's even more expensive than high-P/E Internet picks like Amazon.com (Nasdaq: AMZN) (67), Baidu.com (Nasdaq: BIDU) (78), and Blue Nile (Nasdaq: NILE) (56).

CAPS member showmethefacts also expressed huge reservations over OpenTable:

This stock is now wildly overvalued, with its share price driven by speculators watching charts instead of value. This ALWAYS end badly and when "the market" senses the run is over, a lot of people are going to lose 50% or more of their money practically overnight. As we learned in 2000, there is no "new paradigm." P/E DOES matter. Trees do not grow to the sky. This is a great little company, but share price has wildly overshot any rational projection of earnings.
