It was family night
at Nine Thirty Restaurant inside the W Hotel Los Angeles – Westwood, where Charlie Sheen
shared a friendly meal with brother Emilio Estevez
and his parents Martin and Janet Sheen
. Everyone ordered the salmon except Martin, who opted for a hamburger (without onion). "They were all getting along very well and in good spirits," says an onlooker. "They seemed to be very much enjoying each other's company."
