Are they out of business? The one close to me in Monrovia has closed...
Pretty sure the one in Long Beach, (Lakewood and Willow) is still open but I am going to have to check now.
I've seen two recently (Torrance and Cerritos...or maybe Bellflower) that were still alive and functioning.
Used to stop in at the one on Sierra Ave. in Fontana a few years back. Wasn't to bad. I couldn't find a dedicated website to Spires.
There are two by me, Cherry/Del Amo and Lakewood/Willow, both in Long Beach. Nothing special but they hand form all burgers, and the thousand island dressing and rice pudding are both amazing.
