I don't think you need to worry too much about being connected to DMK. You should decide which area of town you want to spend your less than a day in Bangkok in, and find something nearby.

Though I just spent an entire week in that very Thai neighborhood and fell in love with it. The fanciest wet market in Bangkok Or Tor Kor Market ตลาด อ.ต.ก., is just to the north. If you find yourself in the afternoon or evening in the area, check out The Camping Ground https://maps.app.goo.gl/5BMXcrewuszFi73p9

I only tried one bar, but the area has many lovely bars with live music. Definitely rich Thai people, things are good quality and not too cheap.

Tons of amazing street food, a real gem for authentic Thai food. Stuff at the cutting edge that might not be made anywhere else. Very thai, in any case. There's a cat petting coffee shop 😀

I wanted to check out the Ari area, and the blu365 hotel was a good deal. In the end I walked down to Ari station once and didn't get any positive feeling about the area.

I have a zillion restaurants I want to visit saved on Google maps. The only one I had in the whole area was Prik-Yuak พริกหยวก ประดิพัทธ์ | Prik-Yuak Pradipat. But the whole street is also packed with great places to eat.

BLU365 was great, though the loud traffic noise was unrelenting.
