Le Burger 4304 offers a Steak Frites with 1er Cru flank steak, sauce béarnaise, pommes frites, and peppercorn demi, framed as a more refined take on the classic.[10] The use of flank steak with dual sauces and carefully handled hand-cut fries distinguishes this version as more nuanced and sauce-driven than many straightforward plates.[10] When you eat it, you get a leaner steak with pronounced grain and chew, supported by richly flavored demi and creamy béarnaise, while the thrice-cooked fries deliver a satisfying crunch and absorb the sauces without going limp. Guests who highlight the dish tend to appreciate the attention to detail in both the fries and the sauce pairings, which make it feel like a signature bistro entrée.[10]
