I have a business in Bengaluru. Some of the best food I have had anywhere.
Terrible thing to admit but my 2 business partners always pick the restaurants (and pay), so I often don't register the name.
13th Floor
This is fairly central on MG road. Very unfashionable looking buidling (top of the Hancock it isn't). One of the few rooftop restaurants I would recommend as I am not a big fan of the genre. Not especially great views but the food is pretty good, OK bar etc, and cool temperatures at night. Book and insist on a table on the edge with a view. If they put you in the middle, turn around and walk out!
There is one amazing place set in a sort of garden with 3 or 4 open 'rooms' all on the ground floor. My memory tells me that this is nearby the main business parks where the western companies have their BPO bases. So you may be near there anyway. If I can dig out the name, I will post it here.
One thing. I say Bengaluru. None of my Indian colleagues do! They all say Bangalore!
ha ha ... very authentic ...
Byg Brewski
..... but a good place for plates and plates of starter style food and a micro brewery. Don't be put off by the pics and ref to 'western' food. Stick with Indian options .... full of local IT people if I recall (the Wipro campus is nearby). Byg has two locations, both similar ...
