Rockville location. Silver Diner has positioned itself as the premier destination for families seeking high quality menu options in a friendly diner atmosphere. Today, the Fresh & Local menu uses fresh products from over 15 local producers and offers vegetarian, gluten-free, and low-calorie options. The kids menu has 20 healthier meals and sides that meet strict dietary guidelines set by the National Restaurant Association’s Kids LiveWell program. Of course, classic diner options can still be found on the menu, but with a twist: pancakes using unbleached flour, burgers made from antibiotic and hormone-free beef, milkshakes prepared with milk from local farms, and much more.
