Tsar, as its name suggests, sets out to make its guests feel like real Russian royalty. Drinks are served in fine crystal glasses, old portraits of noblemen cover the walls and the toilets are even encased inside giant, leather-lined thrones. The Russian cuisine on offer is first rate – no doubt Nicholas II himself would have loved the Pozharskaya cutlet a la Pushkin. The staff, food and atmosphere here is a real lesson in imperial elegance.
