The Namaste Cafe brings some of the menu items from Animal Kingdom to the west side. It is classified as Asian on the Disney website and costs less than $15 a plate. Some of the different disney dining plans include the food trucks, so be sure to ask before you accidentally pay out of pocket. (This blog has more information about the Disney Dining Plan and what it covers)
They offer small plates of savory options like slow-cooked beef short ribs, butter chicken and tandoori spiced shrimp.
The plate below looks absolutely delicious. I haven't tried any of their menu items yet, but I will definitely be eating there soon. There aren't usually a lot of guests lined up around the food trucks (their location doesn't help- they're easy to miss if you aren't looking for them) so I've more or less overlooked them in that past. However, Disney sees a lot of potential in them and has made plans for Disney Springs to have a dedicated area called food truck park.
