R.K. Centre is located at Navrangpura, near Vijay Cross Road. I visited them several times and had a good experience.
Food and Presentation: You can find food here tasty. I have never had any complaints yet. Presentation is good. They serve it nicely and with respect. They are quick to serve. I never had to wait for long.
Ambience: Its cool. Its peaceful inside. There is a TV. Its clean, has a wash basin and a towel. Its spacious.
Customer Service: They are friendly, polite and soft-spoken. They pay heed to what you have to say. So, they deserve 4 star ratings for this.
Value for Money: Its budget-friendly. If you are not looking for an expensive restaurant, you can try it. On an average, we have not spend for more than 200 - 300 rupees for 2 people for most of the items we ate.
