This place is a local dive bar.  My friends and I went here because a waitress at Kona Brewing mentioned it.  We had a hard time finding it because it is kind of hidden away in the back of the building that it is located.   Hence, the hideaway name, I am guessing.  The beer selection is pretty limited.  It's mostly cheap domestics.  I don't even think that they had food (or at least not much of a menu).  The song selection is not the best.  They  also make you pay a $1 to sing a song, and the karaoke diva sometimes would disappear.  Some of the people looked kind of sketchy, and one was even dancing crazily behind us when my friend and I were singing Lady Marmalade.  So, why am I giving it four stars?  Because I had a lot of fun here!  You make due with what they have and rock out.  The drinks are cheap.  The bartender is a nice guy, and one of the best parts of this place.  When you sing a song, people sing along.  They even clap for you if you are awful (or awesome).  It makes you feel good!
Review Source:I adore Sam's Hideaway. When ever I am staying in Kona, I always go to Sam's. If you get there around 8-ish the place is lively with karaoke. So much fun. It's never really crowded, which I love, and the lighting is perfect (nice and dim). The bartenders and waitstaff are always really nice.
I like to order rum & cokes with sailor jerry's rum, they never let me down.
My most expensive bill was $45, and that was after my boyfriend and I ordered about 5 (possibly more) drinks each.
Very reasonably priced.
