This is one place that should be recommended for every visitor to Bangalore, either Indian or Foreign. The ambience is out-of-the world, especially if you are fortunate to go there on an evening when you get showers. Though it is open-air, there is protection from rain in the form of awnings which are promptly pulled at the sight of rain. The music is top-notch. They start with soothing instrumental music and turn it on to more livelier-stuff as the night progresses. By then you would have had a couple of drinks and you would definitely enjoy the fast-paced high decibels. Food is good and the service is also great.
If you are a Bangalorean, you must have been there atleast once, else you are not a true one at that! Need I say more!
