The current version will allow you to see the address of the food trucks and order from them (assuming they have preordering menus available). Swipe up from the bottom of the screen to see a list of the trucks. Select a truck (Hoss Burger Truck 1 for an example), then click the circle "Order" button. On the next screen you select "takeout" and find the event that you want to order for.
It's not ideal, but it's a means to an end for now. The map and location list should be added back by the beginning of July.
Thank you for your patience and understanding,
Nashville Food Truck Association
