I was automatically going to vote 'Range of Whiskies' but I first read everyone's posts, just to see what the general concensus was and low and behold...it was the range as the top decider
In Melbourne, Oz I know there are some good bars about town but the trouble is 1. Finding the bars 2. Getting there.
I have yet to enter a true 'Whisky Bar' and my definition of this would be...
upholstered furniture, not bloody plastic chairs and cafe tables!!!!!

seperate areas for both smokers and non-smokers as if by chance I wanted to sample a whisky with my cigar
Actually just before it slips my mind...I have been into a true whisky bar, sorry I forgot...woops

Fidel's Bar @ Crown Casino(but due to the anit-smoking laws and the casino becoming a smoke free venue Fidel's has to move, not sure of exactly if they plan to move or just close shop, it would be a damn shame if it was the latter!!!
I have also been into another bar of which I would definately call a true whiskybar, but I unfortunately was there on business and so didn't get a chance to enjoy the venue for it's real atmosphere - Baranow's is the venue...
Anyway back to the topic...
I would think by having a good range, and not just all the standard stuff but a varying selection of products in both Distillery bottlings and Independants would ultimately intrigue the staff, thus the staff would on their own accord do some research and inform themselves on products, plus it would involve the staff further in conversation with patrons on various products.
Obviously a basic knowledge of serving the various products would be a requirement!!
Anyone out there want to help me start a chain of proper liquor appreciation venues...
