biju is looking for a job in a hindu restaurant in the US. eventually he finds a place. he asks to be sure, and then comes a short dialogue with the boss:

"To Biju he said: “Beef? Are you crazy? We are an all-Hindu establishment. No Pakistanis, no Bangladeshis, those people don’t know how to cook, have you been to those restaurants on Sixth Street? Bilkul
bekaar. . . .”
One week later, Biju was in the kitchen and Gandhi’s favorite tunes were being sung over the sound system.

what exactly does "bilkul bekaar" mean, is it a kind of exclamation?
