A visually striking Royal Exchange restaurant pairing contemporary Korean cooking with sushi and polished service, but its premium pricing, occasional service lapses, and adventurous menu make careful ordering worthwhile.
Jang Restaurant delivers solid food quality and attentive service, anchored by a striking City setting with historic architecture and views that justify its special-occasion appeal. However, inconsistent dish execution and variable service pacing prevent a stronger grade, while unusual review patterns create uncertainty about the reliability of its most enthusiastic praise.
Jang makes a strong first impression: it occupies the Royal Exchange's grand mezzanine, where historic architecture, balcony views and polished tables turn dinner into an occasion. Diners repeatedly describe the setting as beautiful and the welcome as unusually attentive; one reviewer summed it up as a place where the building itself adds something special to the meal. The service is a clear asset, although a minority report slow pacing, rushed clearing or pushy upselling. The cooking is contemporary Korean with Japanese touches rather than a straightforward neighborhood Korean menu. Expect gochujang, doenjang, kimchi, sashimi, tartare, dry-aged beef and carefully styled sauces, with the K-BBQ feast and sushi selections drawing the most enthusiasm. The strongest plates can be excellent, especially the black cod, seafood and sharing barbecue, but the menu is ambitious enough that execution has varied across visits and special menus. It is also expensive: a full meal commonly lands around £70-90 before drinks, with premium selections pushing much higher. For families, this is better suited to a celebratory meal with older children than a casual outing with picky eaters. The menu does include approachable sushi, fried chicken, rice, ice cream and a vegan sushi selection, but there is no clearly listed children's menu and much of the cooking is spicy, raw, fermented or elaborately composed. Afternoon tea offers sandwiches, scones and cakes, making it the gentler family option; otherwise, check preferences carefully before booking.
Area vibe: Dense financial district centered on banking and commerce with a mix of historic landmarks and modern offices.
Safety: Very busy on weekdays with good lighting and foot traffic; quieter evenings and weekends so less activity after dark.
What's nearby: Adjacent to the Royal Exchange, Bank station, the Bank of England, and numerous corporate offices and lunch-focused restaurants.
The menu’s strongest bets range from dry-aged K-BBQ and black cod to sushi selections and a generous sharing feast.
Plan for a polished but costly meal, with adventurous flavors, variable pacing, limited parking, and possible extra charges.
The historic Royal Exchange setting creates a special-occasion atmosphere, although the otherwise polished service can be uneven.
