I usually do not like hamburgers. I have tried many many kinds, and the only one I like is In & Out Burger's, so I was not expecting anything out of ordinary when I visited Island's. I ordered the "Hula" on a wheat bread. It was excellent... exceeded my expectation. My only complaint is you have to order fries separately.. but for a few bucks, you get a huge basket of fries.. so it's worth it!
They have plenty of great cocktail drinks. Lava Flow and Rust something (sorry, I can't remember the name, it's banana cocktail drink) were excellent. Probably the best Lava Flow in the mainland.. made me wish I was sitting by the beach in Hawaii :)
The restaurant gets crowded on weekends, so make sure you come early. But you can alway sit at the bar, which serves full menu and drinks!!!
