I haven't had many Vadais, but this one is simply amazing. I had the prawn vadai ($1) which comes with 2 small prawns and a complementary green chilli. Just out of the fryer, it was crispy on the outside, light and airy on the inside. The prawns lent a delicious moreishness to the vadai, and the dough itself is super tasty - very fragrant without being too heavy handed on the spice. Take it with a bite of the green chilli and this'll be one of the best ways you can spend a dollar around.
