Arby's and Buffalo Wild Wings are joining forces to create a fast-food empire - here's what could change

A spokesperson for Arby's told Business Insider that the acquisition will give it access to different technologies. This could mean that we will see a more efficient ordering system at Arby's.

Buffalo Wild Wings already gives customers the option to pre-order meals online.

Arby's is famous for its curly fries. For some, this is the chain's main draw.

While Buffalo Wild Wings does offer french fries and potato wedges, it could benefit from adding this popular dish to the menu.

Since Arby's CEO Paul Brown took over in 2013, the chain has undergone some major changes, including an aggressive refurbishment effort.

The new spaces are modern, clean, and spacious, and it seems to be resonating well with customers. Arby's reached $3.7 billion in sales in 2016, with $1.1 million in sales per store on average in the US — up 20% from 2013, thanks to some of the changes put in place.

We could expect to see more investment into Buffalo Wild Wings' locations to make them more appealing to customers who are increasingly losing interest in casual dining.

While trends are shifting away from casual dining, there's a chance that Arby's could look at bringing elements of the experience to its restaurants and offer meals that are more suitable for dining in, especially given the restaurants' revamp.

These meals could include more sit-down desserts, which are a big hit at Buffalo Wild Wings.

Food quality has been a crucial part of Arby's turnaround.

Brown repositioned Arby's as a fast-food company that offers good-quality meat, launching a "We Have the Meats" campaign to showcase more elaborate menu items, such as the venison sandwich.

This has helped to lure in millennials. In the two-year period ending in 2015, 18- to 34-year-olds went from making up 38% of Arby's customers to comprising 54%. This could be a good strategy for Buffalo Wild Wings, too.

Another tactic that has helped Arby's to woo millennials is brash marketing.

This approach to marketing, which Brown calls "as non-corporate as possible," has been crucial in attracting these new diners, who tend to value authenticity.

This is something Buffalo Wild Wings could easily take up, too.

Alcohol is an important driver of revenue for Buffalo Wild Wings.

Arby's could look into offering beer in its restaurants as well. Other fast-food chains, such as Shake Shack and Taco Bell, already serve alcohol in certain locations.
