Following a hard-fought public battle over whether Wal-Mart could open a store in Rosemead -- one that spawned recall movements against a mayor and city councilman who supported the development -- the retail giant opened its doors in that city in September.

Is Wal-Mart a good neighbor? Does it help the communities it serves? Why are smaller cities like Rosemead and countless others around the country embracing the chain?

Find answers to these questions and more on Friday at a screening of the film "Wal-Mart: The High Cost of Low Price" at the Oh Happy Days Organic Cafe & Market in Altadena.

Before the screening, Oh Happy Days will serve a meal including a vegetarian soup at 6:30 p.m. for a suggested donation of $5.

The film starts at 7:15 p.m. Friday. Oh Happy Days is located at 2283 N. Lake Ave., Altadena. Call (626) 797-0383.
