If you feel like adding yourself at the last minute then you are welcome to. Just ask for Sanjay's table when you get there.
Tangawizi is an Indian restaurant serving both veg and non-veg food. It has some good reviews and is just short walk over Richmond Bridge and not far from the drinks meetup which I have added on the same evening in Richmond. We've been here before and everyone was happy with the food and service.
Because of the number of maximum people I am allowing for this event, they recommended an early start. But don't break a leg if you running late, join us anyway and order the food when you arrive :)

As usual, I will ask them to split the bill into separate tables and each person is responsible for calculating their owed amount and passing it to the person totaling up the bill on their table. It seems to have worked out well in the past!
