Hello,

I am traveling from the US to London for a few months. I want to take my mom there for a week or two for her birthday since she has always wanted to go there. Unfortunately, she is traditional and eats only Indian food (vegetarian). Is Indian food easily available in London? That could be an issue for her. I eat anything, but I am worried about her diet. Any help is appreciated.

You can visit site London Eating - London Restaurants Guide for search information.

I would like to suggest you to visit these Indian restaurants in London names are given below:
Hason Raja
Chutney Raj
Tandoori Raj
Hope my information is helpful to you.

Tandoori raj offers some really good indian food.

I agree with two restaurants : Chutney Raj, Raj Tandoori. That is where you can have a diet as you desire.
