How about something along the lines of
\documentclass{article}
\usepackage{textcomp}

\makeatletter
\newcommand\menu[1]{\@menu#1\zzz}
\def\@menu#1,#2\zzz{\textbf{#1}%
     \@for\@tmpmenu:={#2}\do{~%
         \textrightarrow\ \textbf{\@tmpmenu}%
     }%
}
\makeatother

\begin{document}
\menu{item1,item2,itemn}
\end{document}
