I would be surprised if anyone under 40 ever made a trip to Hong Kong and didn't eat at least one meal at Tsui Wah. My personal favorites are the Malaysian Curry Beef Brisket and Crispy Buns w/ Condensed Milk. While it can be considered as 'fast food', it never lets me down and I'm never opposed to grabbing some grub there.
