Jinhans next to Renrenle Supermarket on Third Street in the Development Zone, Brazilian barbecue is 38 yuan per person; Hanlixuan next to Wumei Supermarket on the Bund on Shanghai Road, Korean self-service barbecue (grill yourself) is 45 yuan per person at noon and 50 yuan per person in the evening;
There is another one on the second floor of Chinatown, opposite E-Mart, with a buffet of Samba Soup. I haven’t been there but I heard it’s good. The above three stores seem to have different discounts for birthdays.
