Favorite places for first timer

I am planning to visit Bangalore at the end of this month for work and will be free over the weekend. This will be my first time visiting the city, and I wanted to know about the must-visit places and must-try experiences whether it's eatery, park, restaurants etc etc.. I had planned to visit Nandi Hills after watching YouTube videos of the beautiful clouds, but I’m a bit skeptical after seeing the crowds there. So is it worth gng?
