T&T Steakburger, a new "restaurant", is located on the beach in north Kapa'a. It serves burgers, fries and drinks from a small caravan trailer. Covered picnic tables are provided for diners. The only thing between the tables and the ocean is the bike path.
The burgers are excellent—no, outstanding. They are made from beef (bought from Costco) ground fresh daily and the buns are baked locally and hand-sliced. You can get anything you want on them and the ingredients are the freshest available. A really nice attribute is that you can choose the size of your meat patty. I found 1/4 lb to be just fine, as the meat didn't shrink much on cooking.
The fries are not so good IMO. They are freshly cut potatoes, but they are quite limp and, on the day I tried them anyway, the grease tasted old.
A real downside to T&T is that the owner doesn't have his act together about opening times, or even whether to open on a given day at all. I called him to find out his days of operation and then went to dine. It took me 4 tries before I found him open. Then, when I tried to return for a second experience, I again could not find a time when he was open. He is supposed to open at 11 am, which is when I can go, but often doesn't make it until 12 and sometimes not at all.
T&T will be a real gem if the owner can keep the quality level of the burgers as high as they are now, and if he can open his business according to advertised hours.
