Piedmont is in a small and wealthy city in Alameda County in the San Francisco Bay Area. Located in east of Emeryvile and Oakland and is two blocks from Piedmont Avenue in Oakland, it nonetheless has a vastly different climate. Summers are hot, dry and windy. Fact: By the Roaring Twenties, Piedmont was known as the "City of Millionaires" because there were more resident millionaires per square mile than in any city in the United States].
Most commuters to San Francisco's financial district take "casual carpool" in the morning: riders are picked up by drivers hoping to hop in the commuter lane and avoid the $4 toll across the Bay Bridge. The trip is about 25 min. in the morning, and only slightly longer in the evening via AC express bus.
Piedmont does not really have any restaurants within city limits.
However Piedmont is located in the middle of four great restaurant and shopping districts in Oakland.
The Rockridge business district on College Avenue in Oakland caters primarily to young professionals who commute to the city from the Rockridge BART station.
The Piedmont Avenue business district in Oakland was built around the neighborhood of the Kaiser-Oakland hospital.
The Lakeshore Ave./Grand Ave. area just above Lake Merritt and on either side of the GrandLake Theater.
The Montclair shopping district in Oakland also caters to professionals, though its restaurant scene is less attractive than the other three, which feature restaurants organized by many Chez Panisse alums.
From Bart that can be reached by AC 59 & 59A you can either ride train or ride trains to connect to other transit for all over the Bay Area.
