Base
For restrictions, check all meat and fermented ingredients, not just visible pieces.
Heat
Ask what is already in the broth and which spicy additions can be served separately.
Portion
Start with a regular serving and taste it before adding more sauces.
Apply the description
Use the name as a conversation starter, not a guarantee of identical ingredients or preparation. Clarify important details before ordering. For medical dietary restrictions, discuss ingredients and cross-contact separately; an unclear answer does not establish safety.
Questions and answers
Do all vendors use the same ingredients?
No. Recipes, additions and preparation vary. With dietary restrictions, check the actual order, including sauce, broth and garnishes.
