The food at Vong's Thai Kitchen, or VTK, was delicious last time I was there, although it's been more than a year.
The "downscaling" seemed to consist of some changes to the decor, more casual service (the manager said, "We used to bring changes of silverware out on a tray. Now we just hand you a fork") and removing the most expensive items, such as lobster, from the menu.
Otherwise, the food seemed fairly similar to the previous incarnation, and Vongerichten still plays a hand in developing the menus. It's not Thai so much as Asian fusion, with fresh ingredients and zingy flavor combinations.
If they have it, don't miss the passion-fruit souffle.
