During my search for London's best oyster bars (I was writing this piece for About Time), I was directed time and time again to Prawn on the Lawn; a teeny tiny fishmonger in Highbury that also doubles as a seafood bar, so I made it my business to go and see what all the fuss was about.
There's a cellar which takes reservations, but really you'll want to be up in the shop and here they only take walk-ins. It gets busy on the weekends but you can leave your name and number and go to the pub until there's space. You're not far from Upper Street or there's a few around St Paul's Road.
Try to refrain from groping whilst you look at the menu of the day:
I really wanted to eat every single thing on it. It's a seafood lover's dream and the crab with nam pla was very tempting. I was duty bound to try the oyster tasting platter though, which was no hardship. Mike, their friendly fishmonger / chef prepared me a dish of oysters dressed altenately with cucumber and dill, nam pla and salmon caviar and creme fraiche (my personal favourite). Half a dozen were about £15 I think.
They were so good I bought a dozen Carlingfords to take home and do myself, now that I'm adept at shucking thanks to the Wright Bros masterclass. Think tea towel, sharp strong knife and a tight grip. If you're not sure, ask someone there to show you, I'm sure they'll oblige. Again, I think they were only about £1 each.
