Agra is great for vegans since so much indian food naturally plant-based. Dal tadka, aloo gobi, bhindi masala, chana masala all vegan by default. Just specify 'no ghee no paneer' when ordering

Pinch of salt makes dal makhani without butter on request - though purists might argue this isn't the traditional preparation, it's perfectly tasty for those avoiding dairy. Most roti vegan, naan sometimes has yogurt so ask. Street vendors selling fresh fruit around taj perfect for snacks
