Yee it does you need to call management to make arrangements
Yes, it gets pretty crowded. There are private rooms tho.
It depends on the time you arrive. If you get there before 8, you'll be fine. After 10 it'll be very crowded. Another point to note is that you'll be standing room only. The tables in the main lounge are by reservation only.
If you want to be downstairs in the main restaurant area I think you should be fine but you should still call ahead. If you're looking to be up stairs doing karaoke whether in the main area or in a private room you definitely want to call ahead!
