The complete guide to ordering noodle soup in Bangkok — from choosing the stall to customising your bowl.
Choose your noodle type (point at the options or name it), choose your protein (pork/chicken/beef/seafood), choose broth (clear/tom yum/boat noodle), soup or dry.
Add more chilli, ask for less sweet, request extra herbs, say 'no MSG' (mai sai phong churot) — the cook will usually accommodate.
Mix the condiments in small amounts; squeeze lime over the top; don't over-season before tasting; eat quickly before the noodles absorb all the broth.
A bowl under 50 THB is stall pricing; 60–100 THB is sit-down basic; over 150 THB means either premium ingredients or a tourist location.
Leaving food in the bowl is fine — Thais don't clear plates; broth is particularly hard to finish entirely and leaving it is not rude.
