Which restaurant near the public beach in Hikkaduwa should I avoid?

A cafe across from Hikkaduwa's public beach, near the lobster place, disappointed visitors: the kid's ice cream came with ice chunks, tom yum soup was mediocre, and prices didn't match the quality.

At the same place, customers noted staff don't return change when paying cash — you have to insist to get your money back or accept it as an unwanted tip.

There's suspicion that this cafe lists lobster on the menu just to attract customers, while actually serving cheaper crayfish instead.
