Thonglor Soi 25 — Soi Saeng Ngoen and Its Japanese Strip
By Joe Thonglor — Thonglor neighborhood writer & fact-checker · · Last updated:
Thonglor Soi 25 is one of the hardest sois in Thonglor to research. Search the name and you get rental listings — nobody tells you what is actually on the street.
This page covers the rest: the soi’s second name, the district that several websites get wrong, and a venue list built by opening Google Maps and checking each place individually on 17 July 2026 (our team lives in Thonglor — how we verify).
Where Thonglor Soi 25 is — and which district it’s actually in
Short answer: Khlong Tan Nuea, Watthana, Bangkok 10110, per what Google Maps currently shows.
Worth stating plainly, because sources disagree — and it’s a question people genuinely search:
| Source | Says |
|---|---|
| Google Maps (current) | Khlong Tan Nuea, Watthana 10110 |
| Home.co.th, Hipflat | Khlong Tan, Watthana |
| Homenayoo | Khlong Tan, Khlong Toei |
For paperwork or deliveries, go with Google Maps: Khlong Tan Nuea, Watthana. The soi itself runs off Thonglor Road (Sukhumvit 55) on the odd-numbered side, towards the Phetchaburi end.
⚠️ Why this soi is also called “Soi Saeng Ngoen”
This is why researching this soi gets confusing — Thonglor Soi 25 and Soi Saeng Ngoen are the same street.
| Name used | Who uses it |
|---|---|
| Thonglor Soi 25 | The numbered-soi system along Thonglor Road |
| Soi Saeng Ngoen | The older local name, still used in venue addresses and on transit sites |
Several independent sources agree — Moovit’s directions page is titled “ซอยทองหล่อ 25 (ซอยแสงเงิน)”, this venue’s Wongnai page gives its address as “71 Soi Saeng Ngoen, Khlong Tan Nuea, Watthana” with “ซอยทองหล่อ25(ซอยแสงเงิน)” noted in brackets, and condo review site Homenayoo writes “ซอยทองหล่อ 25 (ซอยแสงเงิน) ถนนสุขุมวิท 55”.
Note that the Wongnai address independently backs up the district too — Khlong Tan Nuea, Watthana, matching Google Maps.
What that means in practice: some addresses give only “Soi Saeng Ngoen” with no number 25 at all. If a driver looks blank, say Thonglor 25 — it lands better.
It’s the same pattern as Thonglor Soi 10, which is called Soi Ekkamai 5 and Soi Charoensuk along different stretches.
Getting to Thonglor Soi 25
| From | How | Notes |
|---|---|---|
| BTS Thonglor | Exit 3 → motorbike taxi or red songthaew | Soi 25 is deep into the road — walking isn’t realistic |
| Phetchaburi side | Come in from Phetchaburi and head down Thonglor Road | Useful at rush hour |
| Other transit | BTS Sukhumvit line · MRT Blue line · several bus routes | Per Moovit |
Red songthaews (small shared pickups) run the length of Thonglor Road — cheaper than a motorbike taxi but you wait. The motorbike-taxi queue sits at the mouth of Thonglor near Exit 3.

Nightlife — and the price gap to know about first
Soi 25 is expensive nightlife, not a cheap wander-and-snack street. Most of the headline venues sit at ฿2,000+ per person:

If that’s not your budget, the same soi has cheaper options:
- After TE Time (50/5 Thonglor Soi 25) — cocktail bar, rated 4.9 from 72 reviews, ฿200–400, open until midnight
- Serica antipasti & wine (11–10 Thonglor Soi 25) — rated 5.0 from 64 reviews, ฿600–800, open until midnight
The price range on this one street spans nearly 10×: ฿200 at After TE Time and ฿2,000+ at Klub25 are a few doors apart. Check before you go.

Housing and condos on Thonglor Soi 25
If you searched “Thonglor Soi 25” because you’re looking for somewhere to live, this is the part you want — the soi is better known for housing than for food:
- Chapter Thonglor 25 — a low-rise condo by Pruksa and by far the most-searched thing on this soi. Thai property review site Think of Living describes it as Minimal Luxury styling starting at 3.99M baht; Hipflat lists it as two 8-storey buildings, 288 units total · official Pruksa site
- Chitrapa Mansion Thonglor 25 — studios, with rents listed on Renthub at ฿5,500–10,000; the budget end of the soi
- W8 Thonglor 25 · Baan Lertpaisan · The Pentacles 2 · DVaree Residence Montatra Thonglor — other projects on the soi
The spread on one street is wide: mid-five-figure monthly rooms through to multi-million-baht condos.

Who it suits
Thonglor Soi 25 works well if you:
- Are into Japanese food and karaoke — this soi goes deeper on both than its neighbours
- Want housing options across a wide price range on one street
- Want a Thonglor address off the main road
Maybe not for you if: you want a strollable street full of food options like Thonglor Soi 13 with SEENSPACE. Soi 25 is somewhere you go on purpose, not somewhere you wander into.
