If you want to try Indian, then I recommend Palms of Goa on Charlotte Street. Very very very good southern indian food.
If you are hungering for BBQ, then Bodean's on Poland Street does great pulled pork, ribs, jerk chicken etc.
Gourmet Burger Kitchen does a pretty good burger.
Chinese, try Wong Kei on Wardour Street. They are famously rude to customers there. It's fun.
For a the best coffee in London (imho) Bar Italia on Frith Street.
Steak, DO NOT go to the angus steakhouses you will find many of. They are fucking shit. And only American tourists eat there. There's a Gaucho's at Piccadilly - same chain as the good Amsterdam one.
And if you want the best London has to offer try here:

See you all tomorrow.
