I love Indian food. I live in the San Francisco Bay Area in California, and I have to admit, I'm pretty spoiled when it comes to Indian food...particularly near where I live (Fremont, California), and work (Sunnyvale, California), Indian food is authentic, plentiful, and pretty damn tasty. I've also been to India a few times, mostly in Hyderabad, Andhra Pradesh which has very spicy food.
My traditional benchmark for good Indian food is chicken tikka masala, which is my favorite dish. Where can I find the best version of this in London? I am definitely not afraid of spicy/hot food (the spicier, the better), so I'm hoping to find a version with a good spicy kick, but also a good balance of the other flavors.
I'm staying at the Staunton Hotel near the British Museum, so any good recommendations close by would be appreciated, though I'm willing to travel for the best, as long as it's reachable by public transportation.
