The best restaurants serving Fusion food in Cathedrals Southwark London

Used to love the food at this chain but I won't be returning due to their self pay app which charges 14% discretionary service tip, then asks for additional tip for your server (with the server's name and avatar so you feel guilty for not doing so), then charges 50 pence for YOU to pay by the app which we were told we had to use. Took twice as much time and effort for the customer vs the usual way of politely calling the server over when they're ready and asking for the bill. (She was hanging out by the register and could easily have done so.)
