One of the best Indian vegetarian restaurants in London, Diwana specialises in Bombay-style (a tangy, soft and crunchy ‘party mix’ dish) and (filled crispy pancakes made from rice flour). Solo diners should consider a thali (a complete meal consisting of lots of small dishes). The all-you-can-eat lunchtime buffet (£7) is legendary, and there are daily specials (£6.60).
