Is GrubHub Facebook for restaurant take-out?

Chicago-based GrubHub.com, an online service that organizes restaurant data and creates an easy method for ordering delivery and take-out from restaurants in 13 U.S. markets, received a financial delivery of its own this week. The six-year-old start-up received $11 million in Series C funding from Benchmark Capital.

The company is going to need the cash. According to Amy Le, GrubHub’s social-media manager, the firm plans to double the number of markets it serves. Will Kansas City be one of those new markets? “I can’t disclose the new markets that we’re going to enter in 2011,” Le says. “But we are expanding.”
