Thanks BigMouthinDC! That's very helpful.
Here's a few photos so you can see what I've done today.
It's framed 10' long and 15" in depth. By the time I do overhang, the top should be 10'6" wide, 18" deep on ends, and 24" deep in the middle. So, I think I've framed right into the figures you suggest. It feels pretty steady, but I may still need to put the little short walls on the front side as well.
The isle on either side measures 43.5" now, so after the wall treatment takes an inch and the bar top takes another 3", I should be at about 39.5" for the finished isle. It feels generous at 43.5", so that should work out fine.
In the last photo you can also see the step I framed to the entrance. It looks to simple to me without the radius, so I guess I'll do that after all. I'd like to match the radius on the entry step to the radius on the bar top. I hope it works that way. Oh, same radius on the front stage too.
Off to watch "Atonement".
