The Ritz Carlton boasts a fine range of (admittedly very expensive) eateries on-site and, with a little effort to avoid obvious tourist traps, guests will find that the surrounding area also has plenty to offer diners.
Top-end
Godunov (5/1 Teatralnaya Ploshchad) caters to well-heeled visitors to the Bolshoy Theatre, offering traditional haute cuisine in sumptuously elegant interiors.
Mid-range
Bosco Cafe (3 Red Square) may be slightly over-priced for its relatively basic Italian cafe fare, but it gives diners the chance to eat al fresco right on Red Square in summer. Belaya Rus (14, Bolshaya Nikitskaya Ulitsa) is a traditional Belarussian restaurant, serving well prepared rustic food at reasonable prices. Next door, Shampan (12, Bolshaya Nikitskaya Ulitsa) does not charge as much for its tempting international menu as its lavish interiors would suggest.
Value
Drevny Kitai (5/6 Kamergerski Pereulok) is worth seeking out for low-cost but, by Moscow standards, remarkably good Chinese standards.
