It seems like it's always that little, out-of-the- way place that cooks up the tastiest morsels. Barbara's Cafe on Cottage Road in South Portland is no exception. Set in an old drugstore in Willard Square, this cozy, eight-table cafe serves creative, inexpensive cuisine in a charming, casual atmosphere defined by large windows, high tin ceilings and creaky hardwood floors. Everything is made to order, from the popular "make-your-own" omelettes at breakfast to the salads, sandwiches and burgers. For something a bit more exotic, try the sauteed mussels and lemon lobster broth or the marinated grilled chicken with goat cheese. Regulars rave about the rosemary focaccia often served before dinner (Fridays and Saturdays only).
