BUDDHA BAR is a very COOL concept I think. Personally I have visited the Buddha Bar in Paris, the ambience is superb and gorgeously decorated. They have a huge Buddha statue as a center piece.....extremely empowering!
1) Buddha represents compassion, wisdom, all the goodness one can think of, Bar is a place where people intoxicate themselves with alcohol, flirt with people and sometimes fights happen etc, etc. They represent "Opposite" poles, hence a great nidge for owners to put their name together....got an marketing edge.
2) I have seen buddha statues or images in homes and gardens of Christians, Catholics, and even Muslims, besides the normal places such as temples, altars and homes of buddhist practitioners. I think Buddha is recognised universally as a symbol of peace, harmony and serenity and is the most widely acceptable peace symbol.
So back to the question, should Buddha statue or images be put in bars?
I would, if I am the owner of the bar becasue :
1) Having the statue in the bar will give me a great opportunity to start conversing with customers on subjects relating to buddhism. I can really start from any angle I want, from what is easily preceived as "as a way of life" to "iconography" of the statue (I would even place some buddha statues with their consorts in union posture, why? to provoke more discussion and make clarifications) .... a great way to plant seeds in people's mind and spread buddhist teachings.
2) I want to make Buddha more popular and accessible to people.
3) I want buddha to bless my premises.
4) What better ways to bring buddha to people who may never have a chance to even have a glimpse of his sacred image.
Likewise, it will be cool one day, if we can DS bar, DS tea house, DS coffee shop.........just a thought....would be very COOL!
