I've been here twice and i would say it's OK. In general, I find the food lacks flavour. But I think this is a result of Jamie and his focus on nutrition (aka not using a lot of fat/salt in his creations). For example, I had the mushroom fettuccine and I needed to add salt. I had a bite of my friend's pizza crust and it tasted like cardboard. The mushroom fritti are by far the best thing on the menu here.
Wouldn't be tempted to come back.
