On things with multiple options you have to guess what way they are going to interpret what you are trying to order. And then even if you get through the confusion of ordering, they will more than likely find a way to mess up your order.
3 restaurants, 1 grocer? Shows many food categories, but when I look for a list of stores, I get three restaurants (two in Westport) and one unnamed grocer. If I tap that grocer, it says "this restaurant" is not available for my order and tells me to go back to the list of available places to select a new one.
