Red Lobster is also Darden. There is a Red Lobster less than 4 miles from DLR. Also, Brea is not the closest to DLR for Olive Garden. There's one at the Main Place Mall (Santa Ana) as well as in Orange and Buena Park. All just over 6 miles away.
Brea is a fun little town to come visit and shop though! (Ok, I'm biased - it's my town!)
