London for The Solo Traveller: a Friday-to-Monday weekend

Free and open until 22:00 on Fridays; take the lift to the viewing level for the sunset, then wander the Turbine Hall.

A star-shaped junction of seven streets with a sundial pillar, small shops and Neal's Yard a short walk away.

A Spanish tapas bar built around a counter and with no reservations; sit at the bar and watch the cooks.

Free, and quiet at opening on a Saturday. Head for Van Gogh's Sunflowers, then Turner and Constable.

A tiny udon bar where you sit at the counter and watch the noodles being made; the hot duck udon is a warming bowl.

A compact Impressionist collection, including Manet's A Bar at the Folies-Bergère, in a handsome 18th-century building.

Taiwanese steamed buns with fried chicken and braised pork; counter seats go fast, so arrive before the rush.

Get there for the 8 am start while the stalls are full and the pavements are empty enough to walk.

The salt beef bagel and a tea at the 24-hour bakery, eaten standing in the street like everyone else.

Free contemporary shows in a handsome 1901 building, with a good bookshop and a cafe on the ground floor.

A Punjabi grill where lamb chops arrive spitting on a hot plate; go early on a Sunday and put your name down.

Free, and best at opening: Turner's watercolours in the Clore Gallery and the Pre-Raphaelites in the main halls.

A Victorian pub opposite the gallery, once a prison's warder pub; the upstairs room has a view over the river.
