When in Delaware, try four places in town and one a short drive north. In town, all four are downtown, try the Brown Jug, the Acapulco Mexican Restaurant, Pizza Villa and the Hamburger Inn. I'm a local and don't have specific menu items to recommend since everything
I've eaten at these restaurants is good. I'm partial to the breakfasts and burgers at Hamburger Inn (open for breakfast and lunch only; homemade h'burger buns, cinnamon and pecan rolls, etc.-awesome and CHEAP food and good size servings! Very old, counter dining set-up, say hi to Frankie, the head waitress who's been there as long as I can remember. If you can, park in the city lot behind and walk thru the back door. You walk past the ancient kitchen and can see and smell the baked goods as you go! If allergic to smoke or have a sensitive nose, be forewarned, this place is one of the few rest's nowadays where smokers can congregate. You may smell like grease and cigarettes when you leave, but it's worth it.) Pizza Villa offers pizza, salads and typical Italian dishes-all good. The Brown Jug is open for lunch and dinner, but not bkfst. Their hamburgers, steak sandwiches, pizza, spaghetti, fried mushrooms, fish sandwiches are all good. At Acapulco's, I like the enchiladas.
The short drive north is about half an hour on Rt. 23 (north) to Waldo to the G&R (see the Sterns review in their book, Roadfood.) They're famous for their fried bologna sandwich (bologna sliced thicker than the usual hamburger, served with whatever burger fixin's you want on it), but I like their other fried foods better, their cheeseburgers are great; also chicken tenders, mushrooms, cauliflower, onion rings, etc. I've never had a "greasy" tasting item here!
