  A new method to extract the weak phase $\gamma$ is suggested by exploiting B
---> D K^{(*)} decay modes that are not Cabibbo suppressed, using the isospin
relations, and ignoring the annihilation diagram as usual. Assuming $3 \times
10^8 B\bar{B}$ pair at $B$ factories, one can determine $\gamma$ with
$3-\sigma$ accuracy for 80^o < $\gamma$ < 150^o using B ---> D K modes and for
50^o < $\gamma$ < 170^o using B ---> D K^* modes.
