Durius River Café is a Spanish chain of Café-Wine Shops run by the two-Michelin starred chef Sergi Arola and their first opening in the UK has sensibly been located by the the Thames between High Timber and Northbank, although the river is not really visible from inside due to an inconvenient sea wall.
Prices are more restaurant than cafe with mains starting at £12 and going up to £20 for a plate of Acorn-fed Iberian ham and artisan breads which is probably fabulous but an Acorn-fed Iberian ham sandwich for £7-£8 would be even more fab and help fill the place up.
