Please check out the above link. The last paragraph of the Akal Takhat Hukamnama states that it begs of Sangat to please to UTMOST sathkaar (respect) of Guru Granth Sahib if one is holding a Samagum for any reason. I believe that Sangat does a more than good enough job of this.
Also, to serve liquor, one needs a license. I believe this hall doesn't have one so the alcohol problem is not a question.
GurFateh!
