In England, the only ban on drinking that I am aware of (apart from a Temperance Lodge), is a ban on consuming alcohol in the Lodge room itself. That I was told , was because the Lodge room had been consecrated. The social/festive boards were held in another part of the building and it is usual to have a separate bar. Most Masonic Halls in England have several Lodge rooms and are host to a number of Lodges, Chapters, and Degrees.In Scotland, most Lodges own their own building. Usually smaller than their English counterparts it is common for the Lodge room to be cleared at the end of the meeting and be used as part of the after meeting "Harmony". Having attended several Installations, there also does not seem to be a ban on drinking during the meeting itself!
Thus there is no rule I have come across that would prohibit sensible drinking at Masonic premises. Indeed Masonic Halls in the UK bring in revenue by letting out the premises for birthday celebrations, wedding receptions and other social events, which would be difficult without a bar and an Alcohol Licence.
