Rainbow hotel serves the pathetic chinese. I ordered manchow soup and schezwan rice. The soup was complete liquid. There was no thickness no salt and its taste was different. I had that soup by adding soya sauce. Rice was ok kind but not that bad. Ambience ? I felt like I am in some gala. They have two section non ac and ac. Ac section is descent compared to non ac. Rates are reasonable. I would jot recommend anything go on your own risk as I didnt taste other dishes.
