If I'm going to take the MTR going to Rcmart Mongkok what station and what exit should I take ?
RCMart is located in Kwun Tong (East Kowloon) and they dont have a store in Mongkok.
As for Kwong Wah Street (KWS), you can take MTR to Yau Ma Tei (Exit A2) and walk about 5 mins.
OR
take MTR Mongkok (Exit E2) and walk about 10 mins.
KWS is located between Yau Ma Tei and Mongkok station.

I also google-mapped KWS for your reference:
