The REDCAT Lounge is ensconced at Level P3 of downtown LA's Disney Hall, catty-corner from the Stanley Mosk Courthouse. Besides the parking-structure entrance, it has its own street-level entrance on Grand. Its location makes it the closest wi-fi watering hole (with free wi-fi) to the courthouse (indeed, jurors are routed to the parking lot there when the Music Center parking is unavailable). Unfortunately for non-business users, it also means the parking on weekdays is a maximum of $17, paid in advance -- the same rate as the Music Center across the street.
The bar is an honest-to-goodness booze bar which also serves espresso and tea drinks. When I was there (about 9:45 to 11:00 a.m.), there was no menu posted. The nonfat cappuccino I had was pretty good.
Besides the bar, the rectangular lounge features plush benches and coffee tables around the south and east walls, with some convenient wall plugs. There's also an Imac on a minimalist computer desk, for those who lack laptops.
The lounge is open Tuesday through Friday at 9 am (it opens at noon on weekends), which makes it unavailable to those who want to do work while waiting for an 8:30 a.m. court appearance; but it still provides a haven for those who come downtown for court and have a meeting or other appointment there later in the day. (I hung out there before a noon seminar I gave a half-mile away.)
