Red Robin Conjures Up a Hauntingly Big Burger and Wicked New Margarita for Spooky Season

ENGLEWOOD, Colo., Sept. 25, 2025 // PRNewswire // -- Red Robin Gourmet Burgers, Inc. (NASDAQ: RRGB) is summoning the spirits of Halloween with a frighteningly tasty lineup of limited-time offerings to awaken taste buds from the grave at participating locations.

Red Robin's new Mega Monster Burger, Candied Orange Fizzy Soda and Mad Scientist Margarita. Available at participating locations from Sept. 29 through Nov. 2. 

From Sept. 29 through Nov. 2, Red Robin invites guests to sink their fangs into the new Mega Monster Burger, a monstrous twist on the fan-favorite Monster Double Burger. This beast of a burger comes stacked with three juicy beef patties, six slices of melty cheese, pickle relish, onion, pickles, lettuce, tomato and mayo, served on a black-and-white sesame seed bun. The limited-time burger is served with a bottomless side of choice, and guests can choose from Red Robin's famous Bottomless Steak Fries, Yukon Chips, Side House or Caesar Salad, Steamed Broccoli and more.

Behind every monster is a mad scientist keeping all the bolts and buns in place. Guests can step into the lab with the new Mad Scientist Margarita for only $7.99*. This scary-delicious concoction combines blanco tequila, agave and lime juice. Guests get to mix in the beaker of scarlet elixir (also known as grenadine) tableside.

"Based on the popularity of our recent limited-time triple patty burgers, such as our Gold Medal Burger and Buzzer Beater Burger, along with the larger, exciting trend in beverages, we wanted to go bigger, bolder and just a little bit scarier by introducing the Mega Monster Burger and the Mad Scientist Margarita this spooky season," said Brian Sullivan, executive chef and VP of Culinary & Beverage Innovation at Red Robin. "From dine-in to takeout, Red Robin's got everything you need to ensure every visit is a scream."

Even the youngest of witches and warlocks can get into the spooky spirit with the new bottomless Candied Orange Fizzy Soda. This magical mix is made of candied orange flavor mixed with Sprite® and topped with cold foam.
