When Chanita Chayaluk decided to open her restaurant and wine bar Taan in Chicago, she harbored a clear and deliberate vision: to showcase Thai cuisine in a different light. Reflecting on the local culinary landscape, she noted that the first major wave of Thai immigration to Chicago took place in the 1970s, and a significant portion of the Thai food available in the city still feels anchored to that era. Hoping to break away from outdated expectations, she launched Taan with an adventurous menu featuring dishes like miang, a Northern Thai delicacy made with fermented tea leaves, and a whole, deep-fried fish bathed in a rich fish-sauce caramel.
Yet, running a newly minted dining establishment in the Midwest quickly introduced a unique set of regional hurdles. According to Chayaluk, the lingering ethos of "Midwest nice" creates an environment where operators often try to overaccommodate and appease the masses. During the early days of service at Taan, guests made frequent requests for substitutions and custom modifications driven by personal preferences and dietary restrictions. Chayaluk points out that these constant alterations slowed down kitchen operations and service speed, which ultimately affected not just the kitchen staff, but the overall guest experience.
Operating with a small kitchen and a lean staff, keeping up with the relentless stream of bespoke orders became unsustainable. Chayaluk explains that it frequently felt less like running an independent, chef-driven restaurant and more like operating a fast-casual assembly line. The breaking point arrived definitively when a diner ordered green curry mussels, but requested them prepared "without the mussels."
Faced with the threat of compromised culinary integrity, Chayaluk implemented a strict substitution policy at Taan. She took to social media to broadcast the new boundaries, explaining on Instagram that foundational ingredients like fish sauce and shrimp paste form the very fabric that defines Thai cuisine. Consequently, these essential elements could no longer be removed from any dishes that naturally included them.
Taan’s pushback arrives during a fascinating cultural moment for the hospitality industry. A decade or so ago, demanding menu substitutions was generally frowned upon by culinary professionals and routinely derided as bad manners by food critics. In recent times, however, restaurants across the country report that modification culture has bubbled back up into full force, driven by a complex swirl of societal and economic factors.
Several developments have paved the way for this era of hyper-customization. The proliferation of fast-casual lunch "slop bowl" spots has successfully primed modern consumers to expect a granular, highly detailed level of customization with every single order. Meanwhile, the widespread popularity of cultural movements like Unreasonable Hospitality has reinforced an intensified version of the classic "the customer is always right" mentality. Compounding the pressure is the modern digital ecosystem, where food influencers review meals in real-time, making any deviation from customer satisfaction—including a restaurant’s decision to decline certain dietary preferences—ripe for an immediate, viral takedown.
Couple all of those social pressures with the harsh economic reality that keeping a restaurant afloat in the current financial climate is exceptionally difficult, and it is easy to see why numerous operators routinely give in. Many feel compelled to accommodate specific requests or alter their menus altogether, a phenomenon reflected in broader trends such as the ongoing de-spicification of dishes across urban culinary scenes.
Despite these intense pressures, a growing cohort of uncompromising operators is standing its ground. Alongside Taan in Chicago is New York’s Ha’s Snack Bar, an establishment that proudly announces in its Instagram bio that everything on its menu contains fish sauce, signaling early to prospective diners that compromises are not on the table.
A similar narrative is unfolding in Phoenix, Arizona, at Lom Wong, where substitution and modification requests surged sharply after the restaurant received high-profile national attention. Chef Yotaka "Sunny" Martin was recognized by the prestigious James Beard Awards, and the restaurant earned a coveted Michelin Bib Gourmand designation. According to chef and co-owner Alex Martin, the accolades brought an influx of diners who were unfamiliar with the restaurant’s specific style and traditional service format.
Martin explains that after the awards, they noticed an increase in guests picking dishes apart, asking for modifications, or expressing confusion over why the kitchen did not course meals in a traditional European fashion. He notes that a prevailing European distinction dictates what an award-winning restaurant is supposed to look like, leading many diners to mistakenly equate culinary recognition with a white-tablecloth, customizable dining experience. The team’s response was resolute: that format has never been who they are, and it is never what their restaurant will become.
Following the lead of establishments like Taan, Lom Wong turned to social media to set clear expectations before guests even stepped through the door. They announced that the kitchen would not make substitutions simply to make a dish more familiar to Western palates, and clarified that certain textural choices—such as beef containing gristle or fish being served whole—are fully intentional and culturally authentic.
Alex Martin credits his co-owner and chef as the driving force behind this philosophy, noting that Sunny serves as their guiding light of cultural context. When considering adjustments, the kitchen evaluates whether changing an element compromises the core integrity of the dish. While Lom Wong permits flexibility on minor details—such as offering a mango salad with shrimp served on the side—they firmly refuse to remove beef or shrimp paste from traditional preparations that necessitate them.
Chayaluk adopts a parallel strategy at Taan to accommodate genuine dietary needs without sacrificing the soul of her menu. The restaurant maintains a dedicated vegan, gluten-free option—currently a fried rice dish—that serves as a comprehensive catchall for diners who cannot consume other items on the menu. Rather than offering a lackluster modification of a meat-based dish, Chayaluk ensures that the dedicated alternative is exceptionally flavorful and substantial. It is designed to be a complete meal rather than a mere appetizer or an afterthought.
At both Taan and Lom Wong, front-of-house and kitchen staff are actively encouraged to uphold these firm operational boundaries. Both Chayaluk and Martin emphasize that these policies are designed just as much to protect the peace and mental well-being of their hardworking staff as they are to maintain quality control for the diners.
Although establishing these rules has occasionally sparked minor pushback, proactive expectation-setting before the meal—bolstered by upfront social media messaging—has been overwhelmingly well-received by the broader public. Describing their approach to customer communication, Martin explains that the team kindly reminds guests that while the restaurant respects their personal preferences, those preferences belong strictly to the individual, ultimately steering them toward menu items that naturally align with their needs.
