Finding Siam Green Co Chinatown: Maha Chai Road, Not Yaowarat
Quick answer: where is Siam Green Co Chinatown?
Siam Green Co Chinatown is at 325 Maha Chai Road, Phra Nakhon, Bangkok 10200. It is open daily from 8 am to midnight. The nearest MRT station is Sam Yot (Blue Line, BL30), about 680 meters on foot, and the walk is a straight line along Maha Chai Road once you leave Charoen Krung Road. The phone number is (+66) 098 127 3004. Have photo ID or your passport with you.
One thing worth knowing before you set off: the branch carries the Chinatown name, but its street address is not on Yaowarat Road. It sits in the old city district of Phra Nakhon. Measured on OpenStreetMap in a straight line, the nearest end of Yaowarat Road is about 900 meters south of the branch and the far end about 1.9 kilometers, so do not navigate to Yaowarat and expect to be around the corner.
What is the exact address and how do I find it on a map?
The address is 325 Maha Chai Road, Phra Nakhon, Bangkok 10200. The branch has its own Google Maps listing, and the Google Maps listing opens the pin directly. The pin sits at about 13.7527 north, 100.5048 east.
If you want a reference point on the ground, two well-known restaurants, Thip Samai and Raan Jay Fai, are both within about 25 meters of the pin on the same stretch of Maha Chai Road. Mahakan Fort is about 330 meters to the north. These distances come from OpenStreetMap coordinates, measured as of 2026-11-11.
What are the opening hours?
As of 2026-11-11, the branch is open every day of the week from 8 am to midnight. Hours can change, so if you are planning around a specific time, call (+66) 098 127 3004 first or check the Google Maps listing.
Which MRT station is closest?
Sam Yot station on the MRT Blue Line (BL30) is the closest. On OpenStreetMap its exits are numbered 1, 2 and 3, and Exit 1 is the nearest to the branch. From Exit 1 the walk is about 680 meters by routed street distance, which works out to under ten minutes at an easy pace.
Wat Mangkon station (BL29) carries a Chinatown association, but it is not the closest to this branch. It is about 1.3 kilometers away in a straight line, which is nearly twice the distance from Sam Yot. If you are riding the Blue Line, get off at Sam Yot.
Democracy Monument is about 540 meters from the branch in a straight line and is a convenient landmark if you are coming by road.
How do I walk from Sam Yot station to the branch?
- Leave through Exit 1 and you come out on Charoen Krung Road.
- Walk a short way along Charoen Krung Road, about 15 meters by the measured route, until you reach Maha Chai Road.
- Turn north onto Maha Chai Road, away from Yaowarat, and follow it for roughly 660 meters. The branch is on this road at number 325.
- Check house numbers as you go and use the Google Maps pin for the last few meters.
If you come out of Exit 2 instead, the same routing adds roughly 120 meters, so Exit 1 is the shortest.
The route follows public streets, so take the usual care with traffic and motorbikes, and treat the measured distance as a guide rather than a promise.
What if I am arriving by taxi or ride-hailing app?
Enter the address as 325 Maha Chai Road, Phra Nakhon, Bangkok 10200, or search for Siam Green Co Chinatown and select the pin from the Google Maps listing. Showing the driver the pin on your phone is more reliable than saying the Chinatown name, because the word Chinatown usually points drivers toward Yaowarat Road, which is the wrong area for this address.
If the app asks for a landmark, Mahakan Fort and Democracy Monument are both near the branch, and the pin matters more than either.
What else is near the branch?
All distances here are straight-line figures from OpenStreetMap coordinates, measured as of 2026-11-11. Thip Samai is about 6 meters from the pin and Raan Jay Fai about 22 meters. Mahakan Fort is about 330 meters away. Democracy Monument is about 540 meters.
The nearest named streets in the OpenStreetMap data are Maha Chai Road, Bamrung Mueang Road, Soi Samran Rat and Paribatra Road. Bamrung Mueang Road runs within about 70 meters of the pin, but the branch address is on Maha Chai Road, so follow that name.
