All these are in Sonoma County, which is where I live.

I really like the Tides Wharf Restaurant at Inn at the Tides out in Bodega
Bay. It has many items on the menu that are adaptable for LC, and is one of
the few places I actually get excited about eating.

In Petaluma, JM Rosen's Waterfront Grill has a TON of options on the menu,
one of the few places I go where I actually have several choices to select
from. If you have a sweet tooth, though, beware... you enter right smack
into their dessert display, and it can be a little challenging. They have no
LC dessert options. http://www.jmrosens.com/

Across the parking lot from JM Rosen's in Petaluma is Dempsey's, which has a
nice roasted chicken and will sub extra veggies instead of potatos. There
are usually one or two items in addition to the chicken and salads that you
can eat LC. Although like JM Rosen's it's on the river, it doesn't have as
nice a setting, and only if you are seated outdoors can you see the water.

Il Fornaio in Corte Madera is good, lots of salads and grilled chicken.

Across the street from Il Forniao in Corte Madera is Max's Opera Cafe. Now,
they have tons and tons of LC items... they have a complete LC menu and even
have several LC desserts, all or most of which are sweetened with splenda. I
was told the chocolate dessert was sweetened with Splenda, but considering
the violent diarrhea and stomach cramps it gave me, I believe that it
contains sugar alcohols. So I now stick to the espresso cheesecake. They
have LC bread for sandwiches, an LC chicken liver, olive, and hardboiled egg
appetizer, and about six LC entrees. Portions are huge. Drawbacks are that
the service can be truly, staggeringly slow, so I would never go there if I
was in a rush.

I also like a local restaurant FOR LUNCH ONLY, called Cape Fear Cafe, in the
town of Duncans Mills (near Jenner). Dinner is expensive and impossible for
LC. Don't even try. The tuna salad on the lunch menu is fabulous, and even
without the bun and fries, the burger is very filling. But best of all is
the brunch menu. I get a sort of Benedict they make with sauteed veggies,
hold the potatos, hold the grits (which they use instead of English muffin),
and served with a side of sausage. Yum! (no website)

Hope this helps!
