According to this HuffPo post, it looks like it was quite the feast for the Eat, Pray, Love cast at The French Laundry (the menu is included in the post). Which means, yes, Julia Roberts was included in that dining posse, and hottie Javier Bardem.
Seems the press (E!, Extra, etc.) didn’t do too shabby either: on Thursday night, chef Michael Chiarello hosted a huge dinner for 180 on the lawn at his restaurant Bottega, and recreated some of the dishes in the book.
