Not Alexandra. The stock is made fresh each day based on a recipe known only to the owners. They are drawn from large vats characteristic of Lao Huo Tang 老火汤 herbal soup stores and bear an influence from the same.
Quality and hygiene are both taken care of here. Fresh cuts of meat (chicken, beef, pork and lamb) are sourced from a butcher that supplies Western restaurants.

This ensures that food gets to you ready to eat, not icy and frostbitten like you’ll find elsewhere.
