I am going to be in Washington this October, where are the best attractions right now, I heard of the SPY museum, and of course all the usual suspects, white house, the mall, etc, etc.

Are there some spots that are not all that well know that I should not miss?

What about nice restaurants, not the 4 star that you will be sharing waiters with the sultan of Brunei, but something that DC is famous for?

All suggestions are highly appreciated

Hopefully someone will see this post, usually everyone gathers around the miles section.

Thanks
