L A Weight Loss was in the Forest Park shopping center, which is on Forest Drive, next to Cardinal Newman high school. This place was on the end in between the Piggly Wiggly and CVS. I kept meaning to go back in the daytime and get some better pictures, but you know how that works sometimes.
A bit of googling establishes that the chain is franchaise based and has a line of protein bars and other foods. As with anything, I can find people on the web saying it's great and people saying it's a scam. At any rate, their weight on Forest Drive is down to 0.
UPDATE 4 March 2010: Added full street address to post title.
