Yaowarat Road runs about 1.5 kilometres through the heart of Sampheng-Chinatown, from the Odeon Circle and China Gate at the west end to the Wat Traimit area at the east. By day, the strip is gold shops and dried-goods wholesalers. After sunset, the same street turns into one of Asia's most famous street food scenes, with vendors filling the sidewalks until past midnight.
Our Chinatown branch sits on Maha Chai Road, a few blocks north of Yaowarat in the Phra Nakhon district. The shop is next to Jay Fai, the iconic crab-omelette spot. The nearest end of Yaowarat Road is about 900 meters south of the shop in a straight line and the far end about 1.9 kilometers, so plan on a longer walk or a short tuk-tuk ride. From the east end, near Wat Traimit or Hua Lamphong, you can ride the MRT Blue Line to Sam Yot and walk from Exit 1.
We open at 8am because Chinatown moves on a different clock than Sukhumvit. Morning food crawlers, dim sum runs, monk processions, and tourists heading for the Grand Palace all start early here. The midnight close covers the late-night Yaowarat food scene, when the strip is at its busiest.
If you're combining Yaowarat with the historic district, Wat Pho is fifteen minutes west on foot or a short tuk-tuk; the Grand Palace is twenty minutes; the Reclining Buddha and the river ferry to Wat Arun are both within easy reach. Our Chinatown branch is the natural cannabis stop for any old-Bangkok day plan.
The Chinatown shop draws a different customer than our Sukhumvit branches. We see food crawlers in the late morning and early afternoon, temple tourists in the mid-morning, and the Yaowarat night food crowd in the evening. The early open and earlier midnight close match that rhythm.
Here is how a visit works. Cannabis flower is a controlled herb under Thai Ministry of Public Health rules, kept and sold under medical-cannabis law. We stock cannabis flower in its original labelled packaging, plus FDA-approved CBD and THC edibles and drinks, health supplements, branded apparel, and accessories, and our knowledgeable budtenders walk you through the menu in branch. Every purchase needs a medical-cannabis prescription, form ภ.ท.33 (PT 33), issued by a licensed practitioner, plus photo ID or your passport, and you must be 20 or older. Siam Green is a licensed dispensary, so we guide you and support the process. Public consumption is not allowed. If you are visiting Thailand, a foreign prescription is not valid here and importing or exporting cannabis is prohibited. The Chinatown team knows this neighbourhood, so ask about flower that pairs well with a long Yaowarat food crawl.
