Its one of my favourite place in Bangalore. All of my nightouts in Bangalore had just one ending point and that was Rasta Cafe. The sad part being that they dont serve hookahs any more, but still you can go there for the food plus there hot chocolate is just awesome.
Food is also really nice though I feel the size of servings has gone down in the past year. Attentive and friendly staff. Good for family during the weekdays and weekend mornings. Nights are usually crowded by people looking for a place to eat, chill and hangout after the deadline in the city so you get to see all sorts of people in all sorts of intoxicated state.
Yet if its only friends and you are looking for a drive and a late night eat, this is the place to go. Been there countless number of times and have never been disappointed.
