Hello community.
I was trying to process this image in darktable but it’s a difficult one for me. I like to see yours solutions about the highlight recover, neon lights and colors.
This is was I got after some effort, not enough for my taste.

Greetings from Habana, and TIA.
Bit hard to determine, not having been there, what the colours actually looked like. I see many different light (=colour) sources, so I hope it reflects the real situation.
Not a darktable submission, hope you don’t mind. This is a nice image to play with no matter the editor used…
WOW, It’s so close to the reality. The reds in the place are vivid and shining, I don’t know yet how to get those colors in dt. I don’t use RT but know it’s a great tool in right hands.
Nice result. Thanks.
Yeah, I was curious about those reds in this place. In the, what we in the Netherlands call, Chinese/Indonesian restaurants I often see this red and it is rather vivid/shining. I went with the assumption that this would be somewhat similar, those being dragons and all that 
Nice play, and a little tricky. Here is my version, also in RT 5.8 dev:
It’s tricky indeed, the place receive light from different sources. At the front receive daylight through glass doors of 4 x 5 m and inside they’re lamps with yellow light, beside that a neon, vivid reds, and the kitchen with white lights
Here my try in darktable.
Edit: or maybe a little warmer
This is the best I could do. Would be interesting to try multiple instances of color calibration to fix the kitchen colours, since I supposed they should to be a cooler tone. In my try they are a little green, makes me remember a frame taken out of Chungking Express or Fallen Angels, they use a similar colour scheme in some scenes.

Nice one, I’m going to check the .xmp to take notes from your try. Thanks.
2nd attempt with some Chinese Red added with CC and color match LCH. The mask is crappy…
About to go to bed… 
Saw this one when posted, got sidetracked. Anyway, don’t have spectral data for this camera, so using the libraw-supplied color primaries. I did dig into the metadata for white balance numbers, found three tags, one which I couldn’t completely decipher. Here’s a rendition with what libraw reported as “as-shot”:
and, just pretty standard filmic curve.
The other whitebalance tag, “auto”, had a definite lean to the daylight temp:
A lot less warm. Me, I like the warmth of the first.
