Time Out Tokyo

"Best Hiyashi Chuka Noodles in Tokyo: Yajima - Yajima is located inside Toyosu fish market, and its cold noodle dish is based on a special sauce – the recipe of which hasn’t changed in the past 60 years. The bright yet mild flavour of the sauce makes this an appetising dish, and it's served with shredded seaweed, tender sliced pork and tamagoyaki omelette. It’s been a crowd favourite for decades."
