Allen Diwan's Spice Lab, Indian Gastrobar As the name suggests, this is Allen’s Spice Lab, which means that this is where we experience flavors and spices, textures and ingredients. In addition, it is his own interpretation of the usual Indian food, which touches it a little, so that the dishes are a little lighter, better and simply delicious, using high-quality ingredients. Allen Diwan has a long history of preparing Indian food and has worked throughout Europe.
