Brick Lane curry houses are now an anachronism, fit only for tourists who know no better. I am forced to say this as a aficionado of curry, and having tried many in the UK (and even in Asia). I have been to the best (Probably Indian Rasoi in East Finchley at the moment).
I have been to the Cafe Naz before for the Sunday Buffet, and it was interesting, tasty, had some unusual things (like goat) and was fair value. If you go up and down Brick Lane, the Bangladeshi Restaurants are all now indistinguishable. They all have guys outside telling you they are the best, and you should come in, and they all claim to have won awards. Their menus are pretty similar, their client base is visitor dominated and the opinion of London Residents is that you should go elsewhere, currently to SW17: Brick Lane has had it's day as a restaurant venue, In fact today, when I went there, most of the eating of Bangladeshi food was actually people eating on the street having bought carry out lunches from a market stall.
I went to Cafe Naz, having booked it, having specified that I wanted the Sunday Buffet, and leaving a local telephone number.
When I arrived, the place looked under reconstruction, and only the upstairs was open. There was a lone diner (but I had booked for 1230 which is early by Sunday lunch in London standards).
The staff, who seemed unaware of my booking told me that the Sunday Buffet had been canceled at short notice because of the London Marathon (Still trying to work that one out: maybe all the chefs were competitors?) and there was no buffet. They offered a second rate fixed price menu even though the buffet dishes were there. I explained that I had a specific booking for a specific time for a specific event, had given my full details etc etc. I was met with complete indifference: it wasn't anything to do with them, they did not know about it, and they did not care. No wonder no one else was there.
So I did not get my yummy Sunday Buffet, my wife was incandescent, and and I realize that like so many others, there is no reason to go for Brick Lane Curry ever again. If anyone would like to comment about what they would have done under the circumstances, I would love to read the comments.
So in conclusion, I would commend you not only to avoid Cafe Naz as you may or may not get a meal, and to think about having a curry somewhere else than Brick Lane
