Under GST there is no distinction between restaurant serving alcohol and restaurant not serving alcohol.

The current GST rate which is applicable on Restaurant Service is 5% without ITC. And if your restaurant is located in a "specified location" i.e. in a Hotel having room tariff more than Rs. 7,500 per day, then 18% GST with the benefit of ITC is applicable.

As far as Alcohol is concerned, you need to charge VAT Rate which is applicable in your state. Note that GST is not applicable on Alcohol for human consumption. It is out of the purview of GST.
