Nando's has apologised after a woman from Birmingham ate chicken after ordering halloumi at its Bullring branch.
The lifelong vegetarian said that as soon as she realised she began crying in the restaurant.
Roshni Barot ordered a grilled halloumi cheese pitta but was served a chicken pitta and didn't realise the error until she had eaten most of the meal.
She told the Birmingham Mail: "I wasn't paying attention as I was talking with my friend.
"I never would have thought that I would need to double-check my food. I trusted them and they have let me down. I was in shock and started crying in the restaurant. I cried all night and couldn't sleep."
The manager at the restaurant offered vouchers for a free meal but Barot turned them down.
She added: "I can feel it sitting there in my stomach. I feel like it's not my body anymore. They took away my choice about what to put in my body and now I can't ever say that I have never eaten meat."
A spokesperson for Nando's said: "We deeply regret that a customer was mistakenly served a chicken pitta instead of the halloumi pitta ordered.
"We are currently in contact with the customer and have offered our sincere apologies and are investigating how this has happened to ensure it doesn't happen again."
