Hey isn’t that… everyone’s favorite fictional Vietnam vet, Lt. Dan, er actor Gary Sinise, dining out with friends on Tuesday night?

Sinise, 60, arrived at Old Ebbitt near the White House with three other friends, grabbed a table and split the crab and artichoke dip. The wait staff recognized the celebrity, a frequent visitor to our fair District as he remains a huge A-list supporter of the military, but no one shouted out “Lieutenant Dan” in the “Forrest Gump” voice the Hollywood vet is so used to.

Sinise is in town for Monday’s National Memorial Day Parade which takes place on Constitution Avenue. Actor Joe Mantegna, chef Robert Irvine, Billy Corgan of the Smashing Pumpkins and “American Idol” winner Caleb Johnson are also on the celebrity line-up.

“Part of what I try to do is just draw attention to those we should always remember and never take for granted — our defenders,” said Sinise at a Washington luncheon recognizing his continued support of wounded vets. “If shining a spotlight on me can shine a light on them and their service and what they go through on a daily basis, then that’s the way that I can give back and serve.”
