(SAN FRANCISCO CHRONICLE) — President Barack Obama made a surprise lunch stop today in San Francisco’s Chinatown.

Obama, wearing rolled up sleeves and no jacket, stopped by the Great Eastern Restaurant at 649 Jackson St. to pick up his take-out order, according to the White House Press Pool report.

Unsuspecting patrons squealed in delight when Obama arrived and chanted “Obama! Obama! Obama!” Many left their food behind in the excitement, according to the pool report.
