Lohan High on ... Life

Lindz hit up L.A.'s hot new restaurant Comme Ça last night and -- wtf?? --was extremely friendly with the paps and fans. What gives?

She was more than happy to oblige when a fan asked to snap a photo with her and she even bid farewell to TMZ's photog when she returned to dinner. Maybe the nicotine is helping her mood.
