An English-only ordering policy at one of the city's most famous cheesesteak joints has drawn an official discrimination complaint, but the owner said Monday he won't back down.

The city's Commission on Human Relations alleges that the policy at Geno's Steaks discourages customers of certain backgrounds from eating there, said Rachel Lawton, acting executive director.

Geno's owner Joseph Vento posted two small signs at his shop in South Philadelphia proclaiming: "This is AMERICA: WHEN ORDERING 'PLEASE SPEAK ENGLISH."'

Lawton said that violates the city's Fair Practices Ordinance, which prohibits discrimination in employment, public accommodation and housing. "It's discouraging patronage by non-English speaking customers because of their national origin or ancestry," she said.

Vento, 66, whose grandparents struggled to learn English after arriving from Sicily in the 1920s, said Monday that he isn't discriminating and has no intention of giving in.

"I would say they would have to handcuff me and take me out because I'm not taking it down," Vento said.

He said no customer had ever been turned away because of the policy.

Vento said he posted the sign about six months ago because of concern over the debate on immigration reform and the increasing number of people in the area who can't order in English. The historically Italian community has become more diverse as immigrants from Asia and Latin America have moved in.

Lawton said Vento could be ordered to take down the signs or face fines. The dispute could end up in court.

"Let them do what they want to," Vento said. "When it comes, then we'll deal with it."
