**FOR USE WITH AP LIFESTYLES** **FILE** This Jan. 18, 2009 file photo shows Alice Waters looking over the produce at a farmer's market in Washington. After waiting nearly 20 years to see a vegetable garden planted at the White House, Waters is waiting again. But this time it's to see how many Americans will follow the lead of first lady Michelle Obama, who last week made Waters' wish a reality when she dug a shovel into the South Lawn of 1600 Pennsylvania Ave. to make way for a garden.

Hey, isn’t that… chef/restaurateur Alice Waters and cookbook author and TV host  Joan Nathan at Cleveland Park’s Ripple on Wednesday night.

No pressure, of course, for the Ripple team, including toque Marjorie Meek-Bradley. Waters only practically invented the concept of farm-to-table eating back in the 1970s at her seminal eatery, Chez Panisse.  And Nathan’s considered one of the reigning queens of Jewish cuisine.

The foodie duo, spotted noshing on sweetbreads, pig’s ear, and duck, are in town to host this weekend’s Sips & Suppers benefit for Martha’s Table and D.C. Central Kitchen.
