I specially like the deep fried sauced fish... if and only if the afternoon weather is ever soothing, it will be nice to have the whole fish by myself (yo! sure or not?). Oh well, it is surely impossible. The place is rather improper, stall location is just in front of a cornered 7-11 convenient store at Pudu.
Here I present you the 2 fishes we had. One was deep fried, another was steamed double-sauced (鴛鴦). Based on some other blog, they do serve other seafood and meat too. So, just in case you wish to have more variety, check out others sites.
This is quite comprehensive, http://kyspeaks.com/2010/10/10/thim-kee-steamed-fish-tilapia-at-pudu/, with map and GPS coordinates too.
Encourage to call before visit. They open only day time, not sure if any of the day is close. We tried night before, and it was another stall that operates at that location, not this.
