Dua Residency, Jalan Tun Razak

Have you been to Dua Residency at Jalan Tun Razak? I haven't been there before and I have google and still not sure of this place.

I was told that it is better to take LRT to Ampang Park, then take taxi to go there. I will be going to Delicious restaurant.

Anyway I am not sure of fee charge by cab.
