Oliver first learned to cook in Tuscany and trained at the award-winning Moro. He was Head Chef at Maquis in Hammersmith and, after a short stint in Paris at Rose Bakery, went on to open his café, which he called Konstam after his grandmother, and then his restaurant at the Prince Albert pub, which he also called Konstam.
He featured in BBC2's "The Urban Chef", which focused on his search for local suppliers to provide high quality, seasonal produce for his restaurant. Since then he has worked in various kitchens at home and abroad including Chez Panisse in Berkley, California.
His book, Food for All Seasons (Faber, 2016) - a personal and informative wander through the food year - has been shortlisted for the Guild of Food Writers 2017 Award in the British Food category.
