Arriving around 12:15 a.m., an onlooker tells PEOPLE that the Two and a Half Men star "was dressed casually and grabbed a bite with a woman who he appeared to have a business relationship with."
Sipping on water and munching on fries and a salad, the source says the actor "left about an hour after he arrived and was unbothered by other bar guests while he was there."
