Been there many times.
Karimeen pollichathe and the biriyani is my favorite (highly recommend), and for the meals don’t ever miss the dessert (paysam)-superb.
Also a point to be mentioned from my previous visit is that about their avial... Most of the youngsters hate avial including I, but kumarakoms avial actually tastes like chammandi of sorts, but it does look like avial!! I’m thoroughly impressed with their ability to have turned a hated dish into a praise worthy one!!
It’s a nice Kerala cuisine restaurant with pleasant old Malayalam songs playing. Feel goodalor
