We will be in London for 5 nights at the end of December/ early January. We are looking for places with delicious food that we can go to with 13 and 9 year old daughters. A variety of casual and nice, but hopefully dinner for two 50-100 pounds. We are thinking of a gastropub or two, an italian place, wagamumu and whatever else. Hotel is near Harrods, but we will be at the theater one night and touring about. What can you recommend?
