Thai restaurant organizes menu by blood type

The menu at The Third Floor in Bangkok includes blood type letters to help diners choose a meal that will complement their dietary needs.

In Asia, many subscribe to the belief that blood type should determine people’s ideal diet and exercise regime. Now, a restaurant in Thailand is promoting that idea by organizing their menu according to blood type. Each dish on the menu at The Third Floor in Bangkok is accompanied by the letters O, A, B or AB, to encourage diners to choose a meal that will complement their dietary needs.

The Third Floor offers a full menu of Thai food including plenty of meat, fish and vegetables. Each dish has the relevant blood-type symbol or symbols beside it on the menu, in the same way a V for vegetarian might appear. According to the blood type diet, type Os require a high-protein diet, stemming from their roots in carnivorous tribes, while type As should go meat-free, as their roots in agriculture mean they have a sensitive immune system, and so on.

Are there other ways of organizing restaurant menus, to cater to niche dietary needs?
