Today, Thursday, February 25th, 2010, Ivar’s Seafood outlets in Washington and California are celebrating National Clam Chowder Day by offering a 2-for-1 deal on cups of chowder.   Happily, the deal extends to the Ivar’s Seafood Bar at Seattle-Tacoma International Airport (SEA).  “The airport Ivar’s is open way longer than the Ivar’s in town,” an enthusiastic employee at the airport Ivar’s told me on the telephone on Wednesday, “So you can get that deal starting at 4:30 in the morning.”

You’d think they’d also be celebrating National Clam Chowder Day over in Boston, where the Legal Sea Foods chain is well represented at Boston Logan International Airport (BOS).  But no.  Via Twitter, the folks at Logan Airport told me,that there was “nothing planned. But we can tell you clam chowder is an airport favorite…and available in every terminal at BOS!”
