The conservative think tank American Enterprise Institute (AEI) made the list, along with Kramer Middle School, the law firm of WilmerHale, Holton-Arms School, and National Geographic Society.
Here is what is said about AEI:
Salt-crusted beef tenderloin, whiskey-smoked rack of lamb, Kobe beef, and duck are staples for the red-tie crowd at the conservative think tank in downtown DC - and that's just the buffet. "We try not to get too repetitive," deadpans chef Richard McCreadie, formerly of the Ritz-Carlton, in a Scottish brogue. The high-end grub comes in handy when VIP panelists stay for lunch and McCreadie has minutes to whip the day's chow-line offering into an elegant sit-down.
The magazine has a picture of an AEI meal of charbroiled Maine lobster with marjoram butter sauce in a tomato concasse. Posh.
Here is a previous Think Tank Watch piece on a think tank's strength being measured by its food.
