Red Lobster was our go-to place when I was a teen in the 80s - we thought it was high class! Always got the Neptune Platter because it had a little of everything.
Don't think I've been to one for close to 20 years. Worked for another restaurant company for a while where I ate and drank for free, so just never went anywhere else.
Their quality did suffer quite a bit. Back in the 80s/90s they actually cooked for the most part. Last few times I went in the early 00's I could tell most of it was pre-made and warmed. You can get premeasured and sauced pastas, for example, that you drop in boiling water for a few minutes, pull out, cut the bag and pour onto the plate. Great for speed and portion control; awful for quality and flavor.
