Bangalore has plenty of pubs and bear shouldn't be a problems at all. I don't drink but my friends always rave about Kingfisher....so try that but there are other brands too.

Bangalore is a very safe city but I still wouldn't rcommend a person of non-indian origin to be out alone late in the night in any India city. If you are planning to be out late, get a reliable taxi from your hotel and keep him with you till you get back. Pay for his dinner and give him good tip and he will happy to go out of the way to take your around.

South Indian and north India foods are the most popular food but there are number of places that serve multinational cuisine like Chinese, Thai, Italian, French etc....look for a place in your hotel directory. I too recommend Sunny's been there once great and quite place.

For SgtRyan..there are plenty of hotels and lodges in Bangalore. You can get a decent hotel for $50-70 near MG road. Check this link out http://www.karnataka.com/tourism/bangalore/hotels.shtml .
(1US $ is about Rs40-42 these days)
If you move out a little you may get cheaper options. I forgot the name but there is lodge near the intersection of MG Road and Brigade Road (great locations) that is quite inexpensive. Can't say how clean it will be because I never stayed there. 4 years back it was $20-30 per night. But great location.
