Visiting Vizag in coming weeks. Need some help.

Planning to visit Vizag for 8 days from 2nd of Feb to 10th of Feb.

1. I am confused whether to rent a scooty or not? Like, is local taxi cheap or not?
2. If I should rent a scooty, should I get an extra helmet there? Does police check for the helmet person sitting at the back of scooty/bike?
3. Can you list some famous places to try food in Vizag? It can be veg or non-veg.
4. What is the cheapest option to travel from Airport to RK Beach?
5. Any hotel suggestions. (Budget: 4000 to 6000 Per day)
6. Famous places that you can suggest us to visit.

Thank you in advance.

Note: I am travelling with a friend.
