SUSHISAMBA City (Heron Tower)

SUSHISAMBA takes over the top floors of 110 Bishopsgate (Heron Tower), where an orange tree anchors the Tree Terrace and the City glitters far below. The kitchen fuses Japanese, Peruvian and Brazilian cooking — sushi, ceviche, robata skewers and its signature tiradito — while the bar turns out inventive, theatrical cocktails. Getting up is part of the drama: a glass lift shoots you skyward before the terrace opens out. The Tree Terrace often accepts walk-ins for a drink, which is unusual for a view this high, though evenings and weekends get busy and the full restaurant needs booking. It's a genuine splurge once food and cocktails add up — mains and sharing plates climb quickly — so we rate it best for milestone occasions where the height and the spectacle are the whole point.
