I've actually used it a lot over the years, starting from the mid-90's when I was working downtown.
I've used it for various same-day activities (Dodger games, Hollywood Bowl, Pantages, etc.) to avoid 101 traffic. I also have utilized it as a good meeting point with friends and when I did a few staycations Downtown, instead of $50 overnight parking, I'd leave my car at Union Station.
It's covered (b/c it's underground), freeway-close (especially good for me b/c I live in Long Beach and work in the SGV so my approach helps me avoid congestion points west and north of downtown LA), and seems relatively secure. I've even used it for weekend trips where I drive to Union Station, leave my car, take the Flyaway to LAX and then in return on Monday, where I head to office.
It's hard to beat $8/day!
