FoodChain is a concept app intended to ease office lunch-time struggles (What do you feel like? Who’s in? Are we ordering in or going out? When??). Partnering with ordering services such as Seamless, the app allows a user to start a “plan” and invite others to join in, or simply join other orders. The brand’s look is bright but slightly off-beat, the tone chummy and relaxed…because we’re serious about lunch but not that serious.
