+1 about avoiding Brick Lane. I had an ex-workmate rave about a little joint he knew their. Clip joint would be more like it. Trying to upsell the lamb chomps even though I told them 100 times I don't like lamb chops. Discounts promised at the door and then forgotten. Bills arriving before you finished eating. Ghastly food. Horrible service. Check out the reviews on tripadvisor. This place kept saying "fake review" but they soon had their comments removed.
I got taken to some posh place with a Michelin star in Mayfair a year ago. We ordered off menu as we had an Indian with us that had been there and loved the place. Honestly I thought it was nothing special.
If you are near Canary Wharf try
Lime Restaurant. I've found the food there clean in flavour and good quality.
