Well "hammer" may be a bit excessive but we island hopped last week sharing a vertical selection of the Meteor Vineyard wines with both sommeliers and collectors.
I have really enjoyed watching the food and wine scene explode here over the last couple of years.
On Maui restaurants like Spago at the Four Seasons Wailea, the Lahaina Grill (ask for Richard Olson - one of my favorite sommeliers anywhere in the US) and Merriman's (which has one of the world's most spectucular views) continue to carry the banner of fine dining, with local fish and produce offering a taste of the Island. Oahu's standard bearers like Alan Wong's and La Mer at the Halekulani continue to wow and soon to open Vintage Cave promises to make the high end dining scene even better. Round that out with places like Wolfgang's Steakhouse, BLT Steak and Michel's and you have enough serious food and wine to pack in a week!
And you absoutley CANNOT go to Oahu without delving into both local food (Ono Hawaiian Foods) and poke (Ono Seafood - different place but right accross the street from Oho Hawaiin - will change your life) as well as the incredible range of Japanese food that surpasses anything else in the US. Gaku, Nanzan Giro Giro, Khanatori absoutley kill it.
In terms of wine retail stores - a couple that I love; Wailea Wine in Maui, which our friend Ed Mikesh just purchased from longtime owners Alan and Diane Beaurline, and HASR Wines in Honolulu - one of the greatest collections of Premier Napa Valley wines anywhere!
