Hunting for the Beauty: Heavy-Light Quark Systems on the Lattice

We present selected topics on heavy-light physics on the lattice in order to illustrate the current status of this field. In particular results concerning $f_B$, semileptonic decays, the decay $B \rightarrow K^*\gamma$ and heavy baryon masses are discussed. Special emphasis is paid to the question of systematic effects which stem from the lattice discretization of QCD.
