Bar & Restaurant Vs GST applicability

Dear Sir,

My client is in the business of running of BAR & Restaurant which include food and beverages(alcoholic). Kindly advice on the following questions:

 Q1.   Can we charge GST @ 5% (2.5% CGST and 2.5% SGST) in the invoice and pay to the GST Dept. vide NN.46/2017 CTR, dated 14/11/2017, vide item no.(ii)(a)(i).

Q2.   If I am not eligible to avail vide NN.46/2017 CTR, dated 14/11/2017, vide item no.(ii)(a)(i), then what is the suitable method to apply the GST on my outward invoices.

Q3.   Issuing invoice towards clubbing both food and beverages (liquor)- is it correct ?
