What Film Or Tv Series Is This From?

I remember a woman who was sat in a Chinese restaurant, looking around at the other people. She phones he friends to come and meet her. I think she then walks out of the restaurant when her friend arrives and when she says she was sat in the restaurant the guy looks confused and when she goes back it's a burned out building. It came to light that there was a problem in the kitchen that causes the explosion. She saw it in the past. It's doing my head in and hope someone can help :)
