Underblack
Coffee shop in Chatuchak Market, Saphan Kwai (สะพานควาย), Bangkok
Underblack is a coffee shop in Saphan Kwai, Bangkok, 684 m north of BTS Saphan Khwai station in a straight line. It has only 4 ratings, too few for the 5.0 average to mean much. It publishes no opening hours, so we cannot say when it trades.
Data last updated: 2 August 2026
Where it is
| Straight-line from BTS Saphan Khwai | 684 m, north |
|---|---|
| Rough walk | about 10 minutes, unmeasured |
| Sub-area | Chatuchak Market |
| Within that sub-area | 89th closest to the station of 208 |
| Address as published | QHX2+X3F ตลาดจตุจักร, 10900 |
| Coordinates | 13.79991, 100.55016 |
Distance is measured in a straight line from the station, not along a walking route, and we say so everywhere it appears because the two differ by a lot in this part of Bangkok.
The street it is on
Underblack sits in the Chatuchak market end of the boundary, which is a weekend destination first and a neighbourhood second: much of what is here trades hardest on Saturday and Sunday.
Our dataset holds 208 places in Chatuchak Market. That is a description of the area, not of this business: we hold no description, photograph or menu for Underblack itself, and have not invented any.
Opening hours
Not published. Underblack lists no opening hours in our source data, and we do not estimate them. About a quarter of the businesses inside our boundary are in the same position, which is why our hours-based pages carry a count of what they cannot see.

Common questions
What are Underblack's opening hours?
We do not know. Underblack publishes no opening hours in our source data, and we do not guess at them. This affects roughly a quarter of the businesses in our dataset.
How far is Underblack from BTS Saphan Khwai?
684 m in a straight line, north of the station, which is roughly a 10 minute walk at an unhurried pace. That is a map distance, not a measured walking route: Bangkok sois, the BTS overpass and the Phahonyothin crossings all make the real walk longer.
Where does this information come from?
A map-based business dataset, last refreshed on 2 August 2026, plus figures we compute from it: distance from the station, rank within the category inside our boundary, and the shape of the rating distribution. We hold no description, photograph or menu for Underblack and have not invented any. Everything we do and do not cover is set out on our methodology page.
What this page is, and is not.
Everything above is either a field from our source data or a figure computed from it. We hold no description, photograph, menu or price list for Underblack, so this page contains none, and it contains 4 of the seven computed sections a listing page can have. Pages with fewer than four are not published at all.
Ratings are attributed to our source and dated. They are not our reviews and we reproduce no review text. Our full methodology and coverage explains what the dataset misses.
