Going Away Party (Istanbul)

I am looking for a club to have a going away party and I was wondering if anyone would have any ideas? I am looking for a club that has dancing, drinking, a beautiful view (terrace preferred), and room for my friends to attend.
If anyone can suggest such a place, I would appreciate it and I will go around and start checking such place(s) out. I would like to have it sometime mid to late June, as I will be leaving shortly there after.
Thanks for the memories Istanbul.
Cheers
