Eating at Moody's is a cultural thing. Many locals tend to love it (we are locals, BTW) and so do people from very far away because of its old-timey atmosphere. As much as I want to promote a local legend, I have to advise that people go for the experience and then consider themselves lucky if they order well.
Breakfasts are standard fare (they do have grits on the menu, which I love; they are small grind but tasty enough and not offered at many places in New England). You won't get real maple syrup with your pancakes unless they've changed the product in the last year; I find the coffee almost undrinkable so stick with the juices.
Lunch is pretty hard to mess up and I haven't had a bad one there...again, it's standard fare.
Dinner is standard menu items with specials by the day (eg: meatloaf is always the special on the same day every week) -- hit or miss for quality. My husband loves the roast turkey with fixings, I like the meatloaf and the turkey. The desserts are the high point. Be advised there are no alcoholic drinks available if that's a requirement with your meal.
We have never had a bad waitress. I go there only if someone I'm eating with wants to go there or if my husband has a yearning for it (maybe once every 3 years for breakfast).
For serious foodies I would recommend going for the experience, but don't bother if you see a line (unless you'll never pass this way again and MUST try it). There are much better options in and around Waldoboro (2-3 at the moment in town; drive 15-30 minutes in either direction and you'll find plenty).
If you value your car, do not park in the spots directly in front of the building as you may get hit by people pulling in or by highway traffic as you back out. Use the side lot.
