No, Pizza Express is not halal. Although they have used halal-slaughtered chicken in the past, the presence of pork and other non-halal meats in their restaurants, along with non-halal kitchen procedures, prevents them from offering halal-certified dishes.

Explanation:

This is the response received after contacting them on their official website:

1. Halal-slaughtered Chicken:
   • While Pizza Express has used chicken from suppliers that perform both halal and non-halal slaughter methods, this does not make the entire menu halal.
2. Kitchen Practices:
   • The presence of pork and other non-halal meats in their kitchens means that cross-contamination is possible.
   • Pizza Express kitchens do not operate under halal procedures, which is essential for certification.
3. Supplier Information:
   • Pizza Express sources chicken from suppliers approved by the Brand Reputation Compliance Global Standards and comply with EU or local animal welfare regulations.
   • Where halal slaughter is used, the animals are stunned before slaughter.

Conclusion:

Pizza Express cannot be considered halal due to the presence of non-halal meats and the lack of halal kitchen practices. For those requiring halal food, it is best to choose a restaurant that is fully halal-certified.

And Allah knows best.
