If you want to get plastered, you can buy absurd amounts of alcohol by volume by purchasing cheap vodka and making it palatable by running it through a water filter to remove the bitter contaminants, then soak fruit in it to give it some flavour.
For 30$, you can make yourself enough very nice booze, flavoured to your tastes, as you would be able to get for $300 or so at a bar.
As for the direct question: different bars have different purposes, which is why there are so many different types.
Bars in the financial district are often vehicles to waste money as a social display. Bars in the artistic sector are often vehicles to meet likeminded poor, but cool, artists and misfits. Bars in residential areas are normally places to relax and have a few pints. Bars in the nightlife areas are normally places to meet people. Some bars have good food. Some bars have cheap drinks. Some bars have great music. Some bars have familiar staff.
There's a bar near where I used to live that offers manicures, male model servers and foot rubs. A few streets down is a sports bar which seems to employ exceptionally chesty waitresses. As you might imagine, the target demographic for each is different.
