Arriving in London November 4th for a wedding on the 5th. Guests staying near Elephant and Castle tube station as well as Shoreditch High Street station. Looking for a nice dinner on the 4th for 4-8 somewhere in-between those areas - will hop in cab or on the tube. We don't want to go too far as a few will have jet lag. We all love good food and looking for a place that serves a variety of food [seafood and meat], they will be OK with us eating/drinking and catching up but not a loud pub setting, just a casual yet nice setting/ambiance. An upscale neighbourhood bistro? Done some searches on Chowhound and looked on London food blogs but this is an area I'm not familiar with and not sure where to go/search. Thank you for any suggestions you might have.
