Hi brother JJ,
If the bar you referring to is the Great Southern Hotel then this is the right shop, shop 2 , 741 George street, its at the end of a private laneway and next to a convenient store.
I have a few Melbourne brothers PM me before they cum up looking for suggestions and all of them heading back down south a much happier man. One guy told Vicky if she ever wants a business partner in Melbourne, he wants in.......haha
If you know what the taste of your friend and know which day he wants to visit, i can give you some suggestions
Cheers
