Ah, what memories this brings back. First of all, my first and only visit to "Veeraswamy's Indian Restaurant in London's Regent Street", where the turbanned Sikh on the door and the punkha wallah who kept us cool and aerated during the meal did much to add to the ambience. Sadly all went belly-up when the bill was presented and we read the unforgettable words "For your convenience, a service charge of XX% has been added to the bill; however, please do not let this deter you from leaving a gratuity : may we suggest YY% ?".
The other memory was inspired by the words "loaned [the tandoor] and his staff to a restaurant in Whitfield Street, London". I wonder if this was the Agra, where I first tasted tandoori chicken on which I then became completely hooked, returning every weekend to eat yet another portion of this superb and previously unknown dish. After eating there perhaps a dozen times, my girlfriend Kirsty & I decided to try somewhere else, so went to (I think) somewhere in nearby Tottenham Street. It was a total disaster. We were reasonably certain that they had no tandoor and had to send out for the meal, which when it finally arrived was dry, tasteless and a travesty of the real thing. After that, we went back to the Agra and never went anywhere else again ! Oddly the management in the Agra were not all that helpful, and we regularly had to argue with them to get chapatti with the tandoori chicken rather than the naan they wanted to serve. I can only assume that this was because our meal would then have needed two chefs rather than one, but since we invariably had mushroom bhaji and pilau rice as well, I can't really see what the problem was.
All this took place during the period 1966--1970. Happy days !
