As it happens I picked up a suit and some shirts from the tailor in the Sheraton last week. He's called Johnny tailor and speaks English and chatty. Price very much dependant on what you're after, but he has a good selection. I've no idea how familiar you are with purchasing tailored clothes, but I'd suggest you go in with a firm idea of what you're after.
Anyway, I'm happy with the results, very good fit.
