Cryer, 48, brought along his wife Lisa Joyner while Kutcher, 36, was joined by fiancee Mila Kunis. The foursome was photographed outside of the restaurant as they waited for their cars to be ready, and reportedly shared hugs before going their separate ways.
The outing comes two weeks after it was announced that Kunis will be guest-starring in the CBS sitcom alongside her fiance and Cryer.
Kunis and Kutcher reportedly got engaged last month after one year of dating. The pair met on the set of the 1990s sitcom That 70's Show.
