Honestly... when I am in Hawaii or even when I lived there... I never ate at L&L. Maybe once in a blue moon.. but never regularly.
Since moving up to Las Vegas, I did find myself eating here more often than not. I like the fact that they have lau lau and kalua pig as a regular menu item where Island Sushi has it only as a special.. but that is pretty much all I ever get when I visit L&L. In Hawaii, I'd get their beef stew or curry, but I can easily make that myself now.. whereas lau lau is a little harder.
I like that fact that you can choose to have cabbage or no cabbage with you kalua pig. Depending on I feel, I will order one or the other. Their other menu items like their mahi mahi is okay.. nothing special. I once felt like getting breakfast for dinner -- Portuguese sausage, eggs and rice.. but I could have easily made that at home for waaaay cheaper!
The location is convenient. But since finding out about Island Sushi, I have been choosing them over L&L as of late. If an Aloha Kitchen was closer, I'd go there as well over L&L.
I guess because I'm so used to crappy L&L in Hawaii, that I find it is overrated.
