Manzoor Sons on Dundas St in Saddar might be the one they meant? They make a great suit, like Ambassador, if you know what to ask for. Not the typical stuff people buy here thinking they've bought a 'good' suit just because it's supposed to be some 'Italian' fabric or has a brand label.
Took me a long time to find good tailoring here and the two I've mentioned are very good. But you have to know your stuff before going to them as well, otherwise they will try to do what everyone here tries to do - sell you something you don't really need. A good suit should last a long time and make you look - and feel - great.
A partially cupro (Bemberg) lined suit with a full floating canvas in 2 pieces > Ambassador will charge about 22000/- for stitching alone on that....with good, breathable and lightweight tropical wool the whole thing would run anywhere about 60k to 80k
If you're buying or getting tailored a fused suit, instead of a full or partial canvassed one, then don't bother....fused suits (doesn't matter if it's Armani labeled or Marks & Spencer or tailored) are a waste of money.
