There are several interesting dining options in Zamoskvorechie, although most are a fair walk west of the Aquamarine Hotel.
Top-end
Oblomov (5 1-y Monetchikovsky Pereulok) is considered one of Moscow's finest eateries, offering 19th century grandeur and superbly cooked Russian and French dishes.
Mid-range
Budvar (33 Kotelnicheskaya Naberezhnaya) is a popular beer hall serving imported Czech brews and hearty dishes to accompany them. Louisiana (30 Pyatnitskaya Ulitsa, Building 4) is a kitschy American-style diner that serves decent steaks.
Value
Idel (8 Maly Tatarskiy Pereulok, Building 1) is a only a few steps from the Aquamarine, and offers guests the chance to sample genuine and inexpensive Tartar cuisine.
