Friends and I are regulars there and we notice a lot of other regulars. In short food is healthy, varied and good value for money. It is home cooked which, apart from the nice atmosphere are the reasons I go back. Furthermore, good wine selection again reasonably priced.
They also offer good menus most of the days. Service is friendly but discreetly so.
Sosta is a warm and intimate restaurant serving a variety of authentic Italian dishes.
