Nguyen Son has some of the best bread I've tried anywhere in Asia. I eat their excellent dark bread almost every day. It's quite reasonably priced, especially if you consider value for money.
I also love the broad range of other great products they have: European chocolate, candy, cookies, choya etc. They are all relatively expensive, but Nguyen Son seems to make sure that chocolate is protected from heat on the way from Europe - not all importers do that.
I usually go to Nguyen Son at Kim Ma. Service is very friendly.
