Spotted in this Washington Post article about terror suspects interrogated "under duress at secret prisons":
The Bush administration announced yesterday that it intends to bring capital murder charges against half a dozen men allegedly linked to the Sept. 11, 2001, terrorist attacks, based partly on information the men disclosed to FBI and military questioners without the use of coercive interrogation tactics.
The admissions made by the men — who were given food whenever they were hungry as well as Starbucks coffee at the U.S. prison at Guantanamo Bay, Cuba — played a key role in the government's decision to proceed with the prosecutions, military and law enforcement officials said.
Emphasis added. The NYT's The Lede blog digs deeper, uncovers an In These Times article, and reminds us that there's also a "Starbucks, a McDonalds, a combined Subway-Pizza Hut, a Wal-Mart-like big box store called the Nex and a gift shop" on the Guantanamo base.
