"Kululu has only been open for a few months, propping up the counter of a kosher deli in Hendon called ... Hendon Kosher Deli. Elad and Ella assemble sandwiches the size of new-borns, sourcing challah from Just Kosher in Borehamwood that provides the barest lip service to resistance, letting the fillings speak for themselves. Pairing those fillings is an art form: salt beef, sliced thin as baloney and piled up, should be ordered simply with pickles and mustard. Egg salad was ordered with an outstanding sticky steak and onions, but even better would be sweet hot peppers, saving the egg for three huge schnitzels the width of escalopes; disregard the cold aubergine completely. The salt beef and the steak are £12 and the schnitzel is £10 plus accessories: these are proper prices for proper sandwiches, and the money is going on the superb ingredients rather than the rent. Don’t sleep on it — Kululu is easily in London’s top 5 sandwich shops and can only get better." - Jonathan Nunn
