Jennings started his career at The Green Dragon in Lymm before joining Bohemia in Saint-Helier, where he was part of the team that achieved a Michelin star.
He has cooked with Nigel Haworth and Gary Rhodes and was more recently head chef at Manchester’s well-regarded Grenache and WOOD restaurants.
At 20 Stories he will introduce dishes including grilled mackerel and beetroot salad; and whole Dover sole with brown shrimp butter and burnt lemon.
A separate barbecue menu will be offered on the terrace during the summer.
20 Stories opened in the No1 Spinningfields development in early 2018.
