Sugar-free friendly restaurants in Tokyo
One venue in Tokyo currently clears our bar for sugar-free (tier S to B, confidence at least 0.6). More are in the research queue.
The official homepage states '食品添加物や砂糖を使わず' (no food additives or sugar used). All dishes are made without refined sugar. The ZERO waffle also uses no maple syrup, relying only on natural sweetness. Dedicated kitchen with no sugar on premises.
