I was lucky enough to be in London for twenty days in September-October, 2009. This is one of the most beautiful cities I have ever seen. Transportations are awesome, I loved the double-decker buses and the tube, there are museums at every corner, I loved Madame Tussaunds, restaurants are great, Indian restaurants are every where, there are lots of parks, like Hyde Park, Green Park and St James's Park etc. everything seems much known. People are helpful, architectures are great. No other city makes me feel this way. No place in the world has such a mixture of cultures, history and energy that London have. Go and explore London and you'll understand what I want to mean.
