Food South Indian Fare just across the divide

Among shopping and other things today, ventured with A across the great divide (no not the Thames but Euston Road which is such a wide and confronting road just north of where I live and I haven't faced it before) to a South Indian restaurant.

The food was great and one course was served with a flattened rice flour pancake that was propped up and looked like some sort of hat with little pots of tasty things underneath.

A (seeing arrival of the food): Oh our hats are here to eat...
Paul: Yes they are fancy hats...
A: You could almost wear them at the races in Ascot...
Paul: Oh so is that how you distinguish the Southern Indians at the races? They are the ones eating their hats??

Silly perhaps, but great food, and so close to Warren Street Tube...
