Somewhere for Lunch

I often have to visit London and this is one of my favourite spots for lunch. I don't know the name of the street, it runs from Upper Woburn Place to the junction of Dukes Road and Flaxman Terrace. It's pedestrianised and when you walking down it there is low traffic noise, it's also protected from the wind so you can sit out and have lunch. There are several sandwich shops and bistros.
