Any parking recommendations for Saturday night's game?

I'm driving up from Pittsburgh this weekend, and will be catching the Mavs/Cavs game while I'm there. The game is pretty much the only reason I'll be downtown, though, and I was hoping for parking tips from some of you.

How expensive is parking at QLA?

Any markedly cheaper alternatives within 4-5 blocks? I don't mind walking a bit.

Any recommendations of good, cheap (at least in comparison to arena food) places to eat in the area?
