Flat Iron WaterlooA-

41-45 The Cut, London SE1 8LF · Steak house, Restaurant · Newington

Crowd-pleasing, good-value steak with lively service and fun touches; excellent for quick, affordable steak nights but expect speed, limited veggie options, and occasional service lapses.

The verdict

Flat Iron Waterloo delivers solid A-grade performance through strong food quality anchored by excellent value-for-money steak and responsive, warm service that keeps pre-theatre diners moving smoothly. Occasional temperature misses and modest ambiance prevent grade A territory, though the bustling South Bank location and memorable cone tradition create genuine neighborhood appeal for steak lovers seeking straightforward, unpretentious dining.

One caveat: Vegetarian/vegan options are very limited and some sides use beef dripping
