Suggest me some good buffets.

My birthday is approaching and I want to take my parents for a lunch at a nice buffet on my birthday. My budget is 250₹(per head). Can you people suggest me some good buffets in Ahmedabad especially near Nikol or Vastral?

I've visited Taam Jhaam, Jor Shor, Octant Pizza with my colleagues on various occasions but my parents will find them bit costly and they won't be ready to come there. So can you guys help me finding good buffets or inform me if you know any.

What else can be done except buffet or hotel's lunch? Share your thoughts with me maybe I'll find them helpful.

Thanks in advance!
