For a night of everything that is representative of the Berlin I tend to love, please consider visiting Kindl Stuben in "fashionable" Neukölln.

Good southwestern German food, fairly trendy local and international alcoholic and soft drinks, beautiful people on the nights we have been there and that unmissable "Neukölln look" of large windows, minimalist wooden furniture and candlelights.

Oh, the music is also rather interesting with frequent gigs.
