I bartended for 18 years so I`ll look at it from that end. Do you want a beer and wine bar, a full cocktail bar, with or without a dance floor, a shooter bar, standup, singles, live or taped music? The list goes on. I would imagine this all depends on the laws in your state/province as to which would be allowed. Is there anything else like your bar near by, you don`t want too much competition.
What is the "fad" these days in your area, country, rock, dance, retro for eg? In my area, country was very strong for about 10 years, now it is getting back to classic rock or dance. There is always new bars popping up in my city but they never last very long, some last less than a year, some lasting two or three years. We have one bar that is the exception and it has been around for almost 20 years and still going strong.
You have to look at the long term here and see if there is a future for a restaurant in your area. Remember also, you will not see any profit for at least five years nor will you be able to pay yourself much of a salary. Are you starting from a new building or redecorating an older one? I may live in a different country but I am pretty sure the same "gameplan" applies here.

I wish you all the best in your endevours and I hope I was of some help to you. I have won all sorts of awards for my bartending and was quite well known in my time, so it can be a hoot if everything has fallen into place.
Please remember these three key words too......LOCATION, LOCATION, and LOCATION!

Good luck,

Ron
