OXO Restaurant is a bar in London at Barge House St, London SE1 9PH, on the OXO Tower. It serves dishes such as steak and mac and cheese with views of the Thames and St Paul's Cathedral, and in the evening guests can eat while watching the sunset or the night view of the Thames. Staff guide guests to their seats, remember reservation details, and make use of the views from window seats. The space is large, but the view is the focus rather than the food.
