spike's teriyaki bowl.
I used to LOOOOOVE that place. Went to hell in a handbasket. Luckily though, the son left right before the ship totally sank and opened up B-Man's Teriyaki & Burgers. That made everything great again!
Taco Bell. No enchorito...no peace.
Tip a glass for Pup 'N Taco.
Lastly, Farrell's Ice Cream Parlours. They were the BOMB back when I was a kid, then turned REALLY bad a few years later. In fact, the one in Rosemead turned into Dixie's or something, now it's a fish place. BOOOOOOO!
