4worldlovers: We are a fast-casual “build your own” concept with one focus: to bring back the Great American Burger that was lost in fast food. Guests love the freedom to be their own boss with 30+ ingredients to choose from, including always fresh, never frozen 100% all-natural proteins, 100% grassfed and grass-finished beef, fresh-cut fries, and locally sourced veggies when available.

Simply put, grassfed beef is real meat and provides more dietary protein than grain-fed beef. Grassfed beef is also naturally leaner, lower in calories, contains more omega 3s and omega 6s, and is loaded with natural minerals and vitamins A & E. We take pride in serving burger lovers a premium beef product, raised the old fashioned way as nature intended.


We believe in keeping things simple. Cows should eat grass, poultry should be cage-less, and produce should be grown locally. No growth hormones here. No antibiotics. No cheap filler. Just a delicious burger that uses only grassfed, natural, goodness. That’s what burger lovers deserve.

Bringing back the great American burger that was lost in fast food starts with fresh local ingredients, hormone-free proteins, and you as the boss. From the moment you walk in the door, there’s no stigma around knowing what you like and how you like it. You can boss your burger, bowl, or fries with more cheese, sauce, and topping options than you can shake a stick at.

Guests can choose from countless keto, paleo, vegan, low-carb, low-calorie, and gluten-free options without sacrificing quality.

Our sole focus will never change as we continue to grow: Keep making the best made-to-order burgers and fries possible to keep your taste buds happy in a transparent, eco-friendly, and forward-thinking environment. That’s what burger lovers deserve.


If you want the best burger possible, this is the place for you. You build it the way you like it and everything is fresh and delicious!”
