I'd strongly consider Guisti's (pronounced "juice - tees", LOL. Just learned that)
It's at the end of the Moke North fork. Cool bar, outside dinning, and very rustic. But good food, nice bar, lots of locals (farmers) and lots of food. Now on it's 4th generation, check the pics/history on this link:

This website is a lot of help. Pull down the "Business Directory" menu and select restuarants:

Have you also considered the town of Locke? There's a visitor dock, but you'll ned to reserve a temp berth at the Marina there, with a larger vessl. There's "Al the Wops". Now THAT PLACE has some history, as does the town. Great bar, very rustic but good. Must go there sometime, why not now?
You could take the Sac river up to "the Point",

berth there overnight, nice view with dinner, plus 24 hour fuel. Then continue up to the Sac to Locke, then return down Georgiana slough (with the current, might be all 5 MPH no wake), to the Delta loop. Turn left and go up the Moke North Fork to Guisti's, or turn right and your on the "Delta Loop". River boat, Willow berm, light hose, Korths, etc. Turn right at the Moke mouth on the San Joaquin, then there's the Spind Drift, Happy harbor and more.
Thewn you could head further upriver in the Channel to the Stockton area. Garlic Brothers, etc.
I know large vessels can make this trip without issues, plenty of water on this route.
FWIW,
I'd recommend the breakfast at Korth's, dinner at Moores River Boat, and lunch at Guisti's or Al the WOP.
My opinion, worth blah, blah, blah...
PS Can I come, I'll pay for fuel???? LOL
