The signature Flat Iron steak was tender and perfectly cooked. It cost £15 when I visited in August 2025, and was still listed at £15 when I checked in October 2026. Prices can change, so it’s worth checking the menu before your visit.
My favourite side was the truffled macaroni cheese. It was rich and cheesy, with the truffle flavour coming through, comfort food at its best.
