We visited several pop up and unconventional restaurant veterans in London, including the folks from Duck Soup and Pitt Cue Co. At 10 Greek Street in Soho, we chatted with co-owner Cameron Emirali, formerly of The Wapping Project, a restaurant/art space in a former power station from the 1890s. We sat on the counter overlooking the kitchen area while he gamely made us vegan and vegetarian options not on the menu.
