Prashant Sengar, boss of the Spicy Affair restaurant in Victoria Terrace, Leamington, claimed that six women who made complaints about him to the police were all lying.
But after hearing from his victims, most of whom did not know each other, a jury at Warwick Crown Court found him guilty of seven charges of sexual assault.
Sengar was jailed for 22 months and ordered to register as a sex offender for ten years.
Prosecutor Lee Marklew had told the jury, "Prashant Sengar is a man with wandering hands. He's an arrogant man. He abused his position of authority with these ladies."

Judge Lockhart while sentencing him told Sengar, "You have been involved in a series of offences committed against young women who sought employment at your restaurant or in entertainment. I am sure this was planned activity."
Some of his victims quit after he threatened them with losing their jobs if they continued to rebuff his advances, the Birmingham Mail reported.
