Veeraswamy's.

Situated in Regent Street, London and founded in 1926, Veeraswamy's is reputed to be the oldest Indian restaurant in England.
I remember taking my Mother there for lunch some forty years ago. The food was good, but the ambiance was basic. I remember bearded Sikh waiters in red turbans and white number ten uniforms.
The restaurant is very swish these days. The fare is imaginative and tasty, but I was staggered by the bill. Cocktails were £8 each, enough to turn one teetotal. London is an expensive place.
