The Salt Like is 10 minutes from my house and I never go any more. Plan on a 1 hour wait on a week night, 2 hours on the weekend. The family style "All you can eat" is $20/person for just the meat, not counting drinks and any cobbler you get. And, and quite frankly, the BBQ just isn't as good as it used to be.
A family of 5 would need to commit close to $150 and an entire evening to it. There are lots of places with just as good meat that don't cost that much.
