Existentialist dudes will identify the name from a 1957 album by Thelonious Monk, while an Ella Fitzgerald song lyric chalked on a board confirms that this London original is in fact a jazz bar – or 'jazzu kissa' as such institutions are known in their native Japan. DJ sets on a kickass system cover all forms of the genre, plus world music, reggae, Balearic, soul and leftfield sounds. The minimalist decor is suitably Zen, while drinks encompass anything from rums, mezcal, cocktails, ‘vieilles vignes’ wines and London craft beers to saké and matcha green tea to go with decoratively presented, well-executed Tokyo tiffin: organic salmon, avocado and shiso salad with wafu dressing; soft-shell crab roll; king prawn tempura; beef sashimi; chilli tofu; donburi rice bowls and ‘raw’ desserts such as lime and coconut tart that are guaranteed organic, vegan, gluten-free and so on.
