Yes, of course, you can have the most delicious chicken biryani while visiting the themed restaurant in Chennai, Manam Restaurant. Last week, I visited this place with my family, and the food was delicious. I am sure you will love it too. 

Whether you can get Biriyani in a robot-themed restaurant in Chennai depends on the specific restaurant's menu. While some robot-themed restaurants might focus on international cuisine or a specific type of food, others could very well include Biriyani, given its popularity in Chennai.

To find out for sure, it's best to:

• Check the restaurant's menu online: Many restaurants in Chennai have websites or social media pages where they display their menus.
• Contact the restaurant directly: Call the restaurant and ask if Biriyani is on the menu.

For example, at "Robot Restaurant" in Chennai, the menu features Indian, Chinese and Continental cuisines with a wide variety of options. dineout.co.in

Please note that menus can change, so checking closer to your visit is always a good idea.
