After 40 years, proprietor Quang Dieu retires. COURTESY ALBERT KOEHL By Albert Koehl The Annex is a great place to live, in part because of local merchants like Quang Dieu. For four decades, including the last three at 460 Bloor Street W. in the Annex, Quang owned and operated the Kensington Natural Bakery and Café. The bakery, which officially closed its doors on Dec. 31, specialized in products for consumers with particular food needs or interests or dietary restrictions.
