Although England is where veganism was formed, where the Vegan Society was founded, and where like everyone cool wants to live, its biggest city is kind of weak when it comes to vegan food. It's easy to be vegetarian here -- restaurants still think it's necessary to mark options that are 'vegetarian' instead of marking the much more necessary 'vegan' (seriously, you can tell from descriptions and names what is vegetarian, without fail). But, while there are many wonderful vegan options at omni restaurants, wonderful all-vegan restaurants are few and far between.
Despite the dearth, the all-vegan Manna, in Primrose Hill, London, would still be the best we have to offer even if tons of vegan restaurants existed here. The food is fantastic, mainly comfort food in large portions. So freaking good. And aside from a few service issues aaaaand a few kitchen hygiene issues (we'll get there), there's little else to complain about.
