I used the same Indian Restaurant for deliveries for about 12 years (Zachary's in Hounslow).
The food was absolutely amazing. They did a dish called a chicken Rezala (very hot) which was positively addictive. If I didn't have it for a few weeks I would get withdrawal symptoms.
Then they shut down
In trying to find a replacement I have realised how diverse in quality they are these days. Some of the restaurants I have tried have been truly awful.
Luckily I have now found a good one again.
