“Bars and restaurants continued to merge through the 1990s and 2000s, and that’s a big reason restaurants, on the whole, got noticeably louder. Bars are raucous, and they present a different dining atmosphere from typical sit-down restaurants. As the bar and dining area began to occupy the same space, their clientele and atmospheres combined, and the result was a lot louder than either one alone. Open-concept restaurants and warehouse-style gourmet food courts have made dining out more casual and communal, but getting rid of the walls, ceilings, and soft goods that once defined luxury have also made them noisier.
Restaurant critics and journalists have long complained about noisy restaurants (San Francisco Chronicle food reporters have carried around sound-level meters since the late 1990s), but in recent years the clamor against clamor has reached new heights. Like the open office, the loud restaurant seems to have overstayed its welcome.
That’s because loud restaurants are more profitable.
According to Pearlman, the haute-casual dining trend also helps restaurateurs run bigger and more successful businesses. Constructing interiors out of hard surfaces makes them easier (and thus cheaper) to clean. Eschewing ornate decor, linens, table settings, and dishware makes for fewer items to wash or replace. Reducing table service means fewer employees and thus lower overhead. And as many writers have noted, loud restaurants also encourage profitable dining behavior. Noise encourages increased alcohol consumption and produces faster diner turnover. More people drinking more booze produces more revenue. Knowing this, some restaurateurs even make their establishments louder than necessary in an attempt to maximize profits.”
