Restaurants are only getting smaller, and that’s by design.

With fewer customers eating at restaurants, operators are eyeing more compact locations with dedicated areas for takeout orders.

Restaurants are shrinking. Even though more people are eating out than before, fewer are sticking around to eat their meal in store. With this shift, brands from Firehouse Subs to McDonald’s and Dunkin’ to Pizza Hut are rethinking design for both front- and back-of-house to better accommodate delivery and takeout — a strategy that often includes smaller formats.

When considering design, restaurants traditionally focused on minimum guest count and maximizing seats in a dining room, but these conversations are changing, Big Red Rooster Senior Vice President Josh Broehl told Restaurant Dive. Big Red Rooster is a JLL company that works with retailers and restaurants on experience design, brand marketing, design management and strategy consulting.

“It’s now about throughput. It’s now about how many customers can we serve,” he said.

With multiple avenues to reach customers from delivery to mobile order pickups, there’s less need for a dining room, he said. There’s also financial incentive to reduce — or forgo — the physical dining space. Broehl estimates that dine-in now accounts for about 15% of a typical restaurant’s sales compared to several years ago, when it was roughly 40%.

Restaurants are also analyzing customer traffic flow more closely to accommodate those that want to dash inside for pickup as well as others who want to mull over a menu and then decide onsite, Broehl said.

“We need to make sure those pathways are intuitive and easy, avoiding the bottlenecks. Restaurant design is starting to incorporate different zones where third-party deliveries can do pickups or wait for fulfillment of orders,” he said.

Mobile orders fulfilled onsite are being brought toward the front for quick pickups and are separate from onsite ordering and dining, Broehl said. Shelves and lockers are increasingly popular as well, with the likes of Chipotle, Blaze Pizza and Cava adding shelves. While there were originally concerns about theft or tampering of food left on shelves, that has yet to emerge as a problem, Broehl said.

Needing less dine-in space is opening up options for restaurants. They don’t need to spend as much on real estate costs and can instead use inline spaces within a retail block instead of a standalone location, Broehl said.

“You’ll continue to see that trend where restaurants can take advantage of these more flexible spaces, which will definitely help their operating costs,” he said.

While dining rooms are decreasing in size, kitchens are growing due to the addition of digital orders, he said. That often means having multiple makelines. Previously, there may have been a makeline for dine-in and drive-thru orders, but now some QSRs with drive-thrus are even adding a third makeline to accommodate mobile orders, Broehl said.

A new QSR model

Major QSRs are taking cues from delivery and carryout trends as well. Fast casuals including Cava, Blaze Pizza and Chipotle are testing out drive-thrus for mobile pickup orders. Others, like Firehouse Subs, Subway, Dunkin’, McDonald’s and Caribou Coffee, are eyeing complete remodels and smaller store formats.

Firehouse Subs is testing a prototype that would be a dramatic design shift for the brand. It uses 25% less kitchen space and holds 28 seats compared to a traditional design of 50 seats.

The design also moves the kitchen from the front to back of the restaurant to better accommodate pickups, which have its own designated area. A stackable sandwich steamer, new to the prototype, helps reduce heating time by a minute, and CEO Don Fox told Restaurant Business the new prototype could result in one less person needed each shift.

Firehouse Subs has plenty of motivation to move toward this model. Its off-premise business now makes up more than half of its sales, according to Restaurant Business.

While McDonald’s is in the midst of a major renovation across its U.S. system that will add self-order kiosks, it is also testing a McDonald’s To Go format in London. Customers order using kiosks, staff is mainly back of house and there is no seating. The concept is meant to accommodate only diners on the go.

Pizza Hut is piloting cubbies for pickup orders in California and plans to expand the test into additional West Coast cities next year. These cubbies, aimed to complement its dine-in experience, are placed toward the front of the store and are meant to appeal to customers on-the-go who don’t want to interact with restaurant staff. These moves seem to align with the company’s recently announced strategy of closing 500 units and reopening them with its delivery and carryout-focused format that offers less dine-in seating.

Caribou Coffee is rolling out a small-format concept in Minnesota called Caribou Cabins. These 600-square-foot stores don’t have any dine-in seating, but offer outdoor seating, a drive-thru and a walk-up window. The Cabin stores will offer an expanded beverage menu and a selection of breakfast sandwiches and baked goods. Caribou Coffee is looking to add more locations within the next 24 months, with five opening up in Minnesota initially. The chain will also explore additional store formats in urban and suburban areas.

There could be even more design changes ahead for the dining experience as diner demand shifts. “Restaurants are working to bring the dining experience to customers when and where they are,” Broehl said.

Instead of being tied to a set kitchen, restaurants could potentially serve up meals in a local park or food hall or other community experience, he said. Several chains like Auntie Anne’s and Shake Shack have already done so by launching fleets of food trucks and opening locations at airports and travel plazas.

For consumers, it will only become easier to order out — exactly what restaurants need.
