Like the earth, a sandwich is made of layers and gathers its strength from its meaty core, which pushes condiments toward the crust to erupt and bury fingers in deliciousness. Let rivers of mayo magma run with today's Groupon: for $10, you get $20 worth of sandwiches, salads, desserts, and more at Parkway Deli, located in The Rock Creek Shopping Center in Silver Spring.

Voted Best Deli in DC by the Washington City Paper in 2008 and by Bethesda magazine readers in 2010, Parkway Deli has been layering meats, cheeses, and breads into mouthwatering masterpieces for more than 47 years. A third-generation, family-owned operation, Parkway serves a mammoth menu of savory sandwiches such as the Reuben grill ($9.25) and charbroiled chicken wrap ($7.75), alongside traditional Jewish specialties such as smoked scotch kippers ($7.35), cheese blintzes ($6.45), and hot matzoh-ball soup ($5.25–$7.25). Wake up in the colorful dining room with a hearty breakfast quesadilla ($8.65) or stop by anytime to sample from the complimentary pickle bar and hang with other gherkin fans or those hard-pressed to forget a mermaid's briny kiss.

• Been a favorite spot since I was a kid. Ideal for a weekend breakfast bonding father/child or mother/child and perfect to get a big bowl of matzo ball soup when you feel winter hitting you hard or a cold coming your way. Neighborhood gem and classic establishment. – EvinOBailey, TripAdvisor
