About Denny's

Denny's is a diner chain with 1,500+ locations, serving breakfast all day plus burgers, dinners and kids' meals for dine-in, pickup and delivery.

Its discounts cannot be combined, so the rule for saving is to choose the single best one for each check, whether that's a Booth Reward, the AARP discount or Kids Eat Free.

Denny's traces its roots to a donut stand opened in 1953. Its menu is anchored by the Slam breakfasts, including the Grand Slam, Lumberjack Slam, All-American Slam and Berry Waffle Slam, alongside specialty pancakes and crepes, skillets, melts, salads, steaks and burgers such as the Slamburger. Signature items include Moons Over My Hammy, a ham and scrambled egg sandwich on grilled sourdough, and the Grand Slamwich. The menu also has a 55+ section, a kids' menu, milkshakes and desserts, plus Triple Play combos and family packs.

Beyond the dining room, Denny's offers catering and sells gift cards. Its Booth Rewards program earns 10 Booth Bucks per $1 spent, in-store or online, and 600 Booth Bucks unlock a reward such as an appetizer, side, dessert or kid's meal; members also get birthday and anniversary rewards. The Denny's site also asks guests to donate toward safer treatments for children with cancer.

When shoppers look for Denny's coupons

Denny's coupon searches peak in November, about 1.5× a typical month, and dip lowest in September.

US Google searches, Oct 2025 to Sep 2026. Search interest, not sales.

Denny's shipping, returns and perks

Refunds
The Denny's location that took your online order applies its own policy, so call it soon for a full or partial refund.

Welcome reward

How to use a Denny's promo code

  1. Denny's savings run mainly through Booth Rewards rather than a code.
  2. Join first, in a restaurant, in the app or at dennys.com/rewards, and the welcome Booth Reward gives you a free item on a purchase of $1 or more.
  3. Since discounts cannot be combined, a Booth Reward and the AARP discount won't both come off the same check.
  4. Rewards also skip tax, tip and alcohol.
  5. They don't work on third-party delivery orders, so place delivery at dennys.com/order or in the Denny's app if you plan to redeem.
  6. The AARP discount is in-store only, which makes it a dine-in choice.

If your Denny's code doesn't work

  • Minimum order: "$5 off Your Order of $25 or More" needs an order of at least $25; "$8 Off $30+ Orders on Select Items" needs an order of at least $30.
  • Exclusions: Rewards cannot be redeemed on tax, tip, alcohol, merchandise, donations, gift cards or third-party delivery orders.
  • Combining offers: Discounts cannot be combined.
  • New customers only: Free item (Booth Reward) on a first order (join Denny's Booth Rewards in restaurant, in the app or at dennys.com/rewards; $1 minimum purchase) does not apply to repeat orders.
  • End date: "30% Off Your Order of The Waffle Slam" ends Nov 16, 2026; "20% Off" ends Nov 16, 2026.

More ways to save at Denny's

  • Booth Rewards pays out in food: 600 Booth Bucks get you an appetizer, drink, side, dessert or kid's meal.
  • Spend often enough to reach that before points expire at 365 days.
  • Members also get birthday and anniversary rewards.
  • Families eating in should look for a participating restaurant with Kids Eat Free, since two kids' entrées can come free with one adult entrée of $6+.
  • Gift cards are sold too, though rewards can't be redeemed on buying them.

Denny's questions, answered

How many Booth Bucks does a Denny's reward take?

A Booth Reward takes 600 Booth Bucks. You earn 10 Booth Bucks for every $1 spent in store or online.

Do Denny's Booth Bucks expire?

Points expire after 365 days. Plan to redeem before then if you visit only now and then.

Does the Denny's AARP discount work on online orders?

The AARP discount of 15% off the whole check applies only in store at participating restaurants. It tops out at $10 and doesn't cover online orders.

When do kids eat free at Denny's?

Participating restaurants give up to two free kids' entrées per adult entrée of $6+. The deal is for dine-in only.

Do Denny's rewards work on third-party delivery orders?

Rewards can't be redeemed on third-party delivery orders. Ordering through dennys.com/order or the Denny's app keeps them usable.

Who refunds a Denny's online order?

Call the Denny's location that took the order as soon as possible. That restaurant applies its own refund policy and can give a full or partial refund.
