PILSEN — At least 30 Pilsen businesses closed up shop Thursday as part of "A Day Without Immigrants" in Chicago.

The decision by Pilsen restaurants and shop owners to close came as immigrants from across the country stayed home from workplaces and classes Thursday in an effort to show how important they are to America's economy.

Pilsen and Heart of Chicago businesses that were closed included:

• 5 Rabanitos Restaurante and Taqueria, 1758 W. 18th St.

• BomBon Bakery, 1457 W. 18th St.

"My whole staff asked me not to work. There are a lot of Latinos in the city who want to be part of the movement," said bakery owner Laura Perea, whose bakeries are located in two majority Latino neighborhoods. "As an owner, it's not the best feeling, but I have to understand where they are coming from. I have to support them."

While some Pilsen business owners opted to close, other popular 18th Street spots were open for business Thursday, including Cafe Jumping Bean, La Catrina Cafe and Cantón Regio.

The national Day Without Immigrants movement called for supporters to boycott businesses to illustrate the financial losses that would be felt nationwide if the contributions of immigrants were excluded from the U.S. economy.

Chef Rick Bayless was perhaps the highest profile participant: He shuttered Frontera Grill, Xoco, Fonda Frontera and Topolobampo Thursday.

Other participating small businesses included L'Patron, a popular family-owned Mexican restaurant in Logan Square, and Pete's Fresh Market, a local grocery chain that has several locations in the city.

"A Day Without Immigrants" actions also occurred in cities including Philadelphia, Washington, Boston and Austin, Texas, according to the Associated Press.
