Who has any experience in the bar/restaurant biz?

[STLantny]

I just took a well paying job, selling/maintaining/installing Point of Servce (POS- flat screens, touch screens, av equip, cash registers etc at restuarants/small biz etc) equipment, along with poker, and a few other business options I am working on, I should be out of the 60k debt by the time I graduate, and maybe have a few bucks saved up. I really like selling this stuff, and I dont mind installing it, Ive also networked with a TON of restaurant owners, and have decided that by the time Im 27/28, (23 now), I want to open up a little corner bar, at the same time I open up my own biz (rather than working for someone), in the POS industry. I figure that I will be able to open the bar, after I get some help w/ training from the connections I make, then hire 2-3 bartenders etc to bartend, then I can do my POS thing during the day, and do the GM stuff at the bar at night. How feasible is something like this? How tough is it (time/talent-wise) to make a bar profitable, if its a smallish neighboorhood bar, and thoughts on the rest?
