Environmental health investigators swooped into The Real China restaurant at Gloucester Quays today.
It comes after Emma Harris took her 14-year-old brother Bailey to the eatery for his birthday only to find their chicken undercooked.
An environmental health spokesman said: “Officers have visited the premises and are liaising with the Real China – a follow up inspection will be carried out.”
Inspectors are visiting the premises again this evening.
The restaurant apologised to Emma and said it acted quickly to throw away 15 chickens after the incident on Friday saying staff were extremely busy on the day in question.
The assistant manager who was on duty on Friday called branch manager Everli Li, who later arrived to throw out the chicken.
She said: "I got a call to say people were complaining.
"I came from the other restaurant I manage and threw 15 chickens away.
"Some of our staff do not speak full English and have trouble understanding.
"We threw the chicken out because they did not look well-cooked like they usually are. The chef was desperate and was trying to get the food out.
"As I said Friday was busier than normal. I am sorry for the experience Emma had with the chicken, table, service and cutlery. I will ring her myself to apologise."
