You can't fault Roka on their food or service. The food is extremely fresh, well prepared, and presented. Even though i'd encourage you to try everything on this brilliant menu, if there are 2 things you must do before you die, they are to taste the wagyu beef sushi and the madargascan prawn.
The staff are well versed on the menu, friendly, and true service minded people.
If dining in summer, sit upstairs, otherwise downstairs is very cool and offers some of London's finest cocktails.
