Suggestions for any good eateries?

I will be in Kochi for about 3 days next week, and I need good suggestions on some restaurants or cafes. Big fan of Pandhal and Kunju's jam rolls. Not looking for places where pizzas and burgers get mashed together to become one massive cheesy shawerma, but if there are any good places selling these items separately or any other specific delicacy, kindly suggest. I'm willing to try everything that's palatable and won't make me fall sick.
