Good old Tak Yu is probably one of Hong Kong's oldest existing restaurants... It first opened its doors sometime in the 1920s and after almost 100 years of operation, it's still alive and kicking...
There is nothing fancy or impressive about the décor here, just the usual Cantonese restaurant style: large hall with round tables... The food, however, is great, especially those scrumptious dim sum and dumplings for which people come from far and wide.
Prices are quite moderate: less than HK$ 100 per person in most cases
