I usually don't rate fast food since it's harder to give a rating given the price, expectation and quality.
With Red Lobster, I'd say... if you're looking for cheap seafood and you're okay with it not being the best quality, than Red Lobster is your place! They have all seafoods, quality is good GIVEN the price, and the quantity is good as well.
What sets Red Lobster apart is that MUFFIN that they bring out to everyone. OMG.
