16k in Bangalore

I recently joined an internship and I'm here for 4 months. In this amount what things will you suggest I can do in order to explore the shit out of this city :)

I'll mostly get time on weekends as 9-6 are office timings. Please give some suggestions. I'm a foodie, also into fitness and trying new things 😀

Also where and how can I look for better opportunities in Bangalore. I'm a computer science graduate...
