Lindy is returning to Fourth Avenue with “Thunderbacon Burger Co.”

Mark your calendars. Lindon Reilly’s new burger concept Thunderbacon Burger Co. is tentatively set to open August 1 at 621 N. 4th Avenue. The space formerly housed The B-Line.

“Lindy,” as he’s more commonly known, rose to fame with his first burger-focused restaurant, Lindy’s on 4th. Although he hasn’t been involved with the restaurant that bears his namesake for years, he’s still a burger aficionado through and through. But if you’re hopeful for some sort of Lindy’s 2.0, that will not be the case.

“These burgers aren’t going to be that major gut-buster kind of stuff,” said Reilly. “It’ll be more quality over quantity.”

While final details are still being dialed in, Reilly is in numerous discussions with local artisan food producers, including Cafe Francais for Thunderbacon’s hamburger buns and Forbes Meat Co. for an exclusive ground beef grind.

Reilly looked to both new and old sources for inspiration, including the shuttered Tucson burger stand Shari’s Drive-In and Los Angeles’s Tripp Burger.

“It’ll be diner-style burgers,” said Reilly. “And it will be a small and simple menu.”

Guests can expect double patties (combined about 1/3 pound) cooked through with Sonoran-inspired flavor profile and sides served in a fast-casual atmosphere. Thunderbacon Burger Co. will also offer gluten-free options, vegetarian, and vegan, although Reilly cautions that it’s not a vegan kitchen.

A Thunderbacon Burger Co. website, Facebook Page and Instagram are in the works.
