Once famous as Mike Hannigan of the chartbuster sitcom `Friends` and now better known as the `Ant Man` of Marvel films, Paul Rudd is getting the Twitterati all excited over something far removed from his Hollywood persona: Biryani.

Yes, the star was in British Constitutional Law researcher-turned-celebrity restaurateur Asma Khan`s acclaimed London restaurant, `Darjeeling Express`. Khan could not believe her eyes when Rudd showed up for the restaurant`s Biryani Supper Club on Sunday (it was his second visit to Darjeeling Express this month) and happily dug into the `dum biryani` prepared in the style that is popular in her original home city -- Kolkata.
