Sugar-free friendly restaurants in Vienna
One venue in Vienna currently clears our bar for sugar-free (tier S to B, confidence at least 0.6). More are in the research queue.
The falter. at source explicitly mentions 'zuckerfreie Hauslimo' (sugar-free homemade lemonade). The HappyCow review from Alexandra108 also notes 'Selbstgemachte Bio-Limo-Flatrate ohne Zucker!' (homemade organic lemonade flat rate without sugar). The owner's focus on health and sustainability suggests sugar-free options are available, but the structural evidence is limited to beverages.
