Vapiano

This big German chain has outposts all over the world. This Great Portland street branch - one of three now in London - was their first UK foray, following it up with venues on Bankside and in Soho. 

There's an effort to simplify transactions here. Diners are given a swipe card, with which they use to order items direct from the chefs before paying when they leave. 

The menu is filled with traditional Italian dishes, ranging from antipasti and insalata to pastas, pizzas and a range of specials created by chefs at each venue. Desserts include tiramisu, panna cotta, crema di fragola and ice cream from Green & Black's.
