#### Streszczenie

It is shown that if $G$ is a weakly amenable unimodular group then the Banach algebra $A_p^r(G)=A_p\cap L^r(G)$, where $A_p(G)$ is the Figà-Talamanca–Herz Banach algebra of $G$, is a dual Banach space with the Radon–Nikodym property if $1\leq r\leq \max(p,p')$. This does not hold if $p=2$ and $r>2$.
