Michael had been happy to help out with a friend, be it a helping hand, an ear to listen, or sometimes just some fun. Ash was one of those gals who really needed more fun in her life, and if she wanted Michael around (for whatever reason that may be), then so be it. He may be an ass, but if his friends want him somewhere he'd be there for them unless there were sever extenuating circumstances.

So he waited for her to show up at the restaurant. He knew she was a vegetarian, so he made sure to find a place with a decent amount of vegetarian fare, a little mexican restaurant on the edge of Museum Row near the park.
