Yes, I agree with the Short Attention Span Summary of "No Reservations" from one of the other reviewer, but I was actually surprised by this movie. I really hadn't expected the whole Zoe-angle, and for me that sets this movie apart from so many other Sunday-afternoon-on-the-couch-romantic-dramas.
Kate is a single-minded, brillant, slightly obsessive chef, who loses control of her life and kitchen, when her sister is killed in an accident and Kate becomes the guardian of Zoe, a little girl who really isn't into forel au bleu, but prefers pizza and Nick barges into Kate kitchen chopping and singing opera.
I really like the story line between Kate and Zoe, that really show how not in control Kate is, but it is Nick and Zoe, who steal the focus in "No reservations". They are brilliantly played.
Watch it from the couch on a Sunday afternoon. Have gourmet munchies within reach and get inspiration for your own livingroom-pizza-plateless-safari.
