Manna, situated in London’s picturesque and well-heeled Primrose Hill, has been producing top-notch vegetarian and vegan fare since 1967. Claiming to be Britain’s first vegetarian restaurant, they pride themselves on serving only the tastiest vegetarian food, and their menu is consistently good. This place, which has long been a favourite with the trendy Primrose Hill set, while on the expensive side, shouldn’t disappoint. Those with a gluten allergy are also well taken care of.
