Mama's Fish House: Is perhaps the best (and most expensive) restaurant on Maui. The beach front location is superb and the ambiance (in and out) can't be beaten. The fresh fish selections are excellent. You can get away without paying too much by not having drinks which, in my opinion, are over priced.
Plantation House: Drive up to Kapalua for a nice restaurant with great views. It's right on the golf course. Food is good. Try for a window table. The large windows with ocean and Molokai views are usually open and the breezes are terrific.
Pineapple Grill: Although there are no ocean views, a nice dining experience in Kapalua can also be enjoyed here. Food is very good. Try the bar menu if you're not too hungry.
Gerard's: This is a FINE French restaurant on Lahainaluna street in Lahaina. There are no ocean views but the local Hawaiian atmosphere is excellent. Try the scallops and ask for an outside table on the porch.
Haliimaile General Store: Take a drive to this quaint sugar cane town and enjoy a super lunch or dinner at Bev Gannon's famous dining spot. Its atmosphere is special and you can spot many influential locals here. There are other Gannon restaurants on Maui (especially in Wailea). They're all fine, but I like Haliimaile the best.
Penne Pasta: This quaint, little dining spot is arguably the best buy on Maui. It's located in Lahaina on Dickinson street. The food is surprisingly good and prices are reasonable. Come as you are, bring the whole family and enjoy.
Hula Grill: It's right on the beach or Kaanapali walkway and adjacent to the Whaler's Village shopping area. It emulates the embiance of a Hawaiian home.The food and service are good. Try the fish.
Leilani's on the Beach: Is right next to the Hula Grill (also on the beach) and is owned and operated by the same firm. The terrace/bar area for snacks, light meals and drinks. It's a VERY popular spot for sunset cocktails. Many locals love it. The restaurant upstairs features prime rib among other things and is first rate.
