A Taste of the Bayou   Finally! A restaurant that serves up good, hearty, southern-style cooking right here in Honolulu. Just opened this summer, A Taste of the Bayou is already racking up a list of loyal regulars who can't get enough of the sweet and savory maque choux, the rich and soothing gumbo, the hearty and satisfying red beans and rice and the two-fisted po' boys. If you dare, stay for dessert and try to decide between the bread pudding, the pecan pie and the beignets.  740 Kapahulu Ave. 732-2229. 11 a.m.-2 p.m., 5:30-10 p.m. Tuesdays- Saturdays.
