You saved yourself by vomiting and deciding never to show your face there. Thankfully you didn't get food poisoned, but what about others who might not be lucky enough to spot those worms as you did. I think you should show your concerns to other expats by calling 44266666 (Baldiya) immediately or at least letting others know the name and location of the restaurant.

Also, upload the picture that you snapped of the worms, if you could for others to identify with the kind of worms they should watch out for in foods from restaurants in Doha.
