Rather precariously after a few gulps and Bangalore being a city of 'young' people overwhelmingly due to the job opportunities in IT, BPO/KPO, Research and Bio-Tech, fights are the norm. I'll PM you links to my previous visits to Bangalore where i have covered bars et al, including an extensive trip (my first) in 2007 where i visited the IT parks too.
A sample of the crowd that frequents bars/malls et al in Bangalore. Actually Bangalore's official name is Bengaluru after Mumbai, Kolkata. Chennai etc., where going ethnic has become chic.
Or, where else can you find candy pink vans advertising makeup under a hoarding for booze which is also the name for Bangalore's IPL cricket team owned by India's richest liquor baron, who is based from here and has a worldwide hooch empire.
Here's a link below to the website of the world's 3rd largest liquor empire based in Bangalore!

Also, you can see the construction and infratructure work going on in Bangalore from new buildings to pavements, the city is getting a makeover!. Lousy for drivers and those trying to find kerbside parking!.
