Holborn Dining Room & Delicatessen Restaurant Review: Set in what was Jun Tanaka’s Pearl, Holborn Dining Room is a much sexier space than the name implies. Open all day, it’s the brainchild of Des McDonald and is a first-rate, casual alternative, serving good old British dishes like a London particular (that’s a pea soup). The Deli offers takeaways and there’s an internal terrace for al fresco dining.
