Blimey this is taking me back

My cousin’s girlfriend from the mid 70s straight through to the early 90s was a Bristolian and she’d often take us kids down to Bristol when she visited her mother. She lived on Fishponds Road, right opposite Eastville Park.
Was there a chocolate factory in Bristol? I remember us always coming home with bags of misshapes and damages, I’m sure it was said that Maggie’s sister got them from work.
