Yep. It is right across from the US Air shuttle gates. I usually take the train to DC. Second choice is Delta shuttle. I wasnt getting the ticket myself this time and they have a contract with US apparently. For a variety of reasons the train didnt work this time and when I arrived Wednesday night I noticed the Five Guys there. Made plans to have lunch there when I returned Friday afternoon. Might make me fly US a bit more on shuttle flights. I suppose I could do DL to DC so I can use the Marine Air Terminal at LGA and then US back so I can eat at Five Guys
