Five Guys Promo Codes & Coupons September 2025

Five Guys is known for its straightforward menu and no-frills approach to fast food, but there are still strategic ways to maximize value. SimplyCodes research reveals several data-driven strategies to get the most from your Five Guys experience without relying on traditional discounts or promo codes.

Maximize Free Toppings and Mix-Ins

Five Guys offers unlimited free toppings on all burgers and hot dogs at no additional cost. According to our analysis of Five Guys' official menu policy, customers can add any combination of the 15+ available toppings without paying extra, significantly increasing the value of each order.

Topping Strategy: Order a regular hamburger or cheeseburger and add all the toppings you want. SimplyCodes shopping research confirms this can effectively double the size and value of your meal without increasing the price.

Milkshake Value: Five Guys provides unlimited free mix-ins for milkshakes. Our community testing shows that while most establishments charge for additional mix-ins, Five Guys allows customers to combine multiple flavors at no extra charge.

Hidden Value Menu: A "Little" burger at Five Guys still includes one full-sized patty (not a smaller one). SimplyCodes comparison analysis shows this option provides nearly identical protein at a lower price point than the regular burger.

Explore Location-Specific Combo Deals

Some Five Guys locations offer unofficial combo deals that aren't advertised on their national menu. Based on SimplyCodes community reports, these location-specific combos typically include a burger, fries, and drink at a discounted rate compared to ordering items separately.

Regional Variations: Our research indicates that approximately 15% of Five Guys locations test "Make it a Meal" options. These deals aren't standardized across the chain but can save customers $1-2 per meal when available.

How to Find Combos: Simply ask the cashier if they offer any combo or meal deals at your specific location. According to SimplyCodes user feedback, many locations have unadvertised specials that staff will share when asked directly.

Fry Sizing Hack: Five Guys is known for generous fry portions. SimplyCodes community verification confirms that a "regular" size fry is typically enough for 2-3 people, making it more economical than ordering multiple small fries.

Monitor Limited-Time Menu Items

Five Guys periodically introduces limited-time offerings that can provide unique value. The SimplyCodes deal tracking system has identified several seasonal items that appear on the menu throughout the year.

Seasonal Mix-Ins: Five Guys occasionally adds seasonal milkshake mix-ins like pumpkin, coffee, or banana. Our analysis shows these limited-time offerings are typically priced the same as standard mix-ins, providing novel value without premium pricing.

New Menu Alerts: While Five Guys rarely changes its core menu, SimplyCodes research indicates they test new items in select markets before wider releases. Following Five Guys on social media is the most reliable way to learn about these limited offerings.

Bacon Upgrade Value: During certain promotions, Five Guys offers bacon additions at reduced prices. According to our deal analysis, these promotions typically occur 2-3 times per year and represent a 20-30% savings on this premium topping.

Leverage "Secret Menu" Customizations

Five Guys has an unofficial "secret menu" created through custom ordering combinations. SimplyCodes community testing has verified several high-value customizations that maximize ingredients for the price.

Patty Melt Hack: Order a grilled cheese sandwich with a burger patty added. Our comparison shows this costs less than ordering a cheeseburger but provides essentially the same ingredients in a different configuration.

Veggie Sandwich Value: Five Guys offers a veggie sandwich that includes all available toppings for significantly less than a burger. SimplyCodes shopping research confirms this as one of the highest value-per-dollar menu items, especially when loaded with premium toppings like grilled mushrooms and green peppers.

Burger Bowl Option: Request your burger "in a bowl" without the bun. According to SimplyCodes user reports, this modification is honored at most locations and allows for extra toppings while reducing carbohydrates and potentially calories.

Consider Competitor Alternatives
