Fans of sustainable eating will soon have another option in Midtown. Otarian, a new vegetarian concept conceived in Australia (though initially launching in New York and London), is taking over the old Momo Sushi space at 927 Eighth Avenue. Designed with the environment in mind, the new restaurant plans to be "the first restaurant chain in the world to have a carbon footprinting system on its menu. When you order a veggie burger, there will be a statement about all of the emissions saved by your vegetarian meal compared to its non-vegetarian counterpart."
