Establishments are ranked in order of the cost of a set lunch, grouped according to the number of courses included and colour-coded by region. The most affordable venue is the Hand and Flowers in Marlow, where two courses will set you back £15.
If you scroll down to the bottom of the larger image you will find the Fat Duck - Heston Blumenthal's flagship - where the set lunch consists of a whopping 14 courses and comes at an appropriately pricey £180!
20 restaurants are not included in the graphic since they either do not serve lunch or offer only an a la carte lunch menu. These establishments are listed at the very bottom of the full size image.
