R.J. Lee, the 1960 founding, and the move to I-40
Robert Joseph "Bob" Lee was an Amarillo-area restaurateur with experience in the regional steakhouse business when he opened the original Big Texan in 1960. The first location was on the old Route 66 alignment in west Amarillo — substantially smaller than the current property and oriented toward the steady traffic of Mother Road travelers moving between Oklahoma City and Albuquerque. Lee's marketing concept from day one combined serious Texas steakhouse food with a strong showmanship aesthetic; the building's frontier design, the western-themed staff costumes, and the rapidly-introduced 72-oz challenge were all parts of a unified entertainment-restaurant approach that was unusual for 1960 and became influential across the broader American roadside-restaurant industry.
The 72-oz steak challenge was introduced within the restaurant's first year of operation. Lee's stated origin story is that he overheard a customer boasting that he could eat "the biggest steak in the house," and Lee built the marketing concept around that boast — anyone who could eat a 72-ounce sirloin plus shrimp cocktail, baked potato, salad, dinner roll, and butter within one hour would receive the entire meal free. The challenge generated immediate regional press coverage and grew into a recurring national-television feature across the 1960s and 1970s, with crews from network programs visiting the restaurant to film attempts.
The construction of Interstate 40 across the Texas Panhandle through the 1960s and early 1970s gradually replaced Route 66 as the primary east-west traffic corridor. Lee responded by relocating the Big Texan to the current I-40 East location in the early 1970s — a calculated bet on the interstate-traveler market that proved correct. The current building was designed from the ground up as a roadside icon visible from the interstate, with the exaggerated façade, the massive signage, and the deliberate kitsch aesthetic all calculated to capture the attention of drivers at 70 mph. The strategy has worked for fifty years.
