I recently took a flight from Honolulu to Las Vegas. In coach class they were serving Filet Mignon with assorted vegetables or Cheese Ravioli. It was accomanied by mixed greens with a Mango Vinaigrette and some fruit as dessert. On the flight SNA-HNL they served either Miso-chicken with vegetables or a lasagna. All accompanied by a caesar salad and finished with a chocolate cake. In coach they also serve one complimentary Mai-Tai per passenger. Prior to landing one gets fresh baked chocolate chip cookies with milk. The meals were served on porcelain and I think the service was better than the one that I usually experience on these routes with United. They definitely come around more often to offer drinks. There was also a snack (nuts)/drink service on the flights SNA-LAS and LAS-SNA.
Now to the First classe service. Since I didn't fly first, I only got a glimpse of what they were doing, but was able to get a menu on the return flight (SNA-HNL). There was apparently also a quick breakfast service on the flight LAS-SNA, but I don't know what they served there.
The menu for the Transpac flight was created by Alan Wong (it says Westcoast to Hawaii on it, so I assume it is served on all flights (OAK-HNL, OAK-KOA, OAK-OGG and SNA-HNL).
It features a Fruit Medley, then chilled shrimp with avocado, papaya and cherry tomatoes with papaya seed dressing.
After that it features either grilled salmon with ponzu and shiitake mushrooms, snow peas on capellini noodles or braised shortribs with taro.
As I said before, I can unfortunately not give any ratings on the quality of food offered. The wine selection was Mumm Cuvee Napa Brut Prestige, Kunde Estate Chardonnay, Rutherford Hill Merlot Napa Valley, Sebastiani Sonoma Cabernet Sauvignon and Brancott Vineyards Marlborough Reserve Pinot Noir (from New Zealand).
The catering was (as far as I could see) provided by Gate Gourmet in HNL and LSG in SNA. I don't know the service provider in LAS.
