Can't go wrong with oxtail soup (aka Bulalo) for late night cravings after a night out on the strip. Located inside California Hotel in Downtown Las Vegas a few miles away from the strip, it is worth the drive. Make sure to go here between 11pm to 9am to take advantage of their Graveyard Specials. 1/2 lb NY Steak for only $6.99 that will not disappoint. And of course the Oxtail soup that completes any meal. There could be a long wait at times to dine in but its totally worth it.
Don't forget to validate your parking so its free.
