Very Southern California Casino's

We're planning a long day trip and thinking about visiting those far south casinos we've never experienced before. We live in north Orange County so just never make it that far south. We hit all the Palm Springs area casino's in a day trip a few years ago and had a lot of fun.

Anyone have any thoughts on the following casino's? I've been to Barona, but years ago. How are their comps for 1st time visitors? Anything like Valley View that gives you a free buffet? I have this affinity for not paying for food when gambling.

Golden Acorn Casino
Viejas Casino
Sycuan Casino
Barona Casino

Thanks!
