Unless they're Hindu........... in which case it's most probably quorn. LOL
What about Thai? Thai's the only 'ethnic' restaurant I'll eat in, you'll break me if that's hallal......
Its not just ethnic restaurants you need to worry about unfortunately, you could eat in an english restaurant and theres still a chance youre eating halal.
The biggest issue is cruelty but theres also the fact that you have to be muslim to work in a halal slaughterhouse so it could push non muslims out of the meat industry.
