Thing to di in The Hague
There are a lot of Irish Pubs in The hague which I always like, for clubbing you don't want to go to the Hague, Rotterdam is the place to be.
For diner I would recommend "De zwarte Ruiter" but then again, I don't know what you like.
I used to work in the Hague for 2 years and I live in Rotterdam, if you need additional info please let met know.
Regards,
