When Chanita Chayaluk decided to open her restaurant and wine bar Taan in Chicago, her primary ambition was deeply personal and deliberately ambitious: she hoped to showcase Thai food in a different light. Reflecting on the culinary landscape of her adopted city, Chayaluk notes that the first wave of Thai immigration to Chicago largely took place in the 1970s, leaving a lasting impression that means a great deal of the Thai food available in the area still feels frozen in that era. When she opened her doors in September, she introduced a vibrant, contemporary menu that boldly featured items such as miang, a traditional Northern Thai dish made with fermented tea leaves, alongside a whole, deep-fried fish lacquered in a rich fish-sauce caramel.
Yet, running a modern restaurant in the Midwest comes with its own distinct cultural quirks. According to Chayaluk, the pervasive regional ethos of being "Midwest nice" often translates into a compulsive desire to overaccommodate and appease the masses at all costs. In the early days of service at Taan, this cultural tendency manifested as an overwhelming wave of guest requests for substitutions and dietary modifications. Diners routinely asked for ingredients to be omitted or swapped to suit individual preferences and dietary restrictions, a trend that quickly began to take its toll on the back-of-house operations.
As Chayaluk explains, these constant alterations would slow down service speed and kitchen efficiency, negatively impacting not just the staff, but the overall guest experience in numerous ways. With a small kitchen and a tight-knit team, keeping up with the barrage of bespoke orders proved nearly impossible. It reached a point where the operation felt less like an independent, soulful restaurant and more like an assembly-line fast-casual chain. The breaking point arrived definitively when a diner placed an order for green curry mussels, but specifically requested them "without the mussels."
Faced with the threat of compromised culinary integrity and operational gridlock, Chayaluk took a decisive stand. She implemented a strict, limited substitution policy at Taan, taking to Instagram to communicate directly with her clientele. In her public statement, she emphasized that foundational ingredients like fish sauce and shrimp paste are the fundamental fabric that defines Thai cuisine, and therefore, they could not and would not be removed from any dishes that inherently include them.
This clash between uncompromising culinary vision and relentless consumer customization is not happening in a vacuum. A decade or so ago, asking for menu substitutions was generally frowned upon by the culinary establishment and frequently derided as bad manners. Recently, however, independent restaurants across the country report that substitution culture is bubbling back up, and this time, it is arriving in full force.
A complex swirl of cultural and economic factors has converged to bring the industry to this juncture. The proliferation of fast-casual "lunch slop bowl" spots has successfully primed modern consumers to expect an intricate, highly detailed level of customization with every single order they place. Meanwhile, the massive cultural footprint of books and philosophies like Unreasonable Hospitality has further popularized an intensified version of the old "customer is always right" mentality, encouraging diners to demand perfection tailored exclusively to their whims.
Compounding these pressures is the rise of social media influencers entering the food-review space. Today, the choice by a restaurant to decline certain dietary preferences or customization requests is frequently treated as a grievance ripe for an immediate, viral online takedown. Couple all of that relentless pressure with the harsh economic reality that it is extraordinarily difficult to keep a brick-and-mortar restaurant afloat in the current financial climate, and it is easy to understand why several operators have simply given in—either yielding to hyper-specific guest requests or altering their menus altogether, a phenomenon reflected in the broader culinary trend known as the great de-spicification of menus.
Amid this tide of concession, however, a growing number of independent operators are choosing to stand their ground. Alongside Taan in Chicago, establishments like New York City’s Ha’s Snack Bar proudly announce their uncompromising stance right in their social media bios, letting patrons know upfront that virtually everything on the menu contains fish sauce.
A similar dynamic has unfolded at Lom Wong in Phoenix, Arizona, where chef and co-owner Alex Martin notes that substitution and modification requests have ramped up significantly after the restaurant began receiving broader national attention. Last year, chef Yotaka "Sunny" Martin was recognized by the James Beard Awards, and in August, the restaurant was honored with a Michelin Bib Gourmand designation.
According to Alex Martin, the influx of accolades brought an influx of new guests who were not entirely familiar with the restaurant’s ethos. They had more diners picking dishes apart, asking for modifications, or expressing confusion over the restaurant’s service style, such as why the courses were not paced in a traditional European fashion. There exists a pervasive European distinction of what an award-winning restaurant is supposed to look like, leading people to incorrectly equate that recognition with a formal, white-tablecloth establishment. In response to these expectations, Martin and his team remained steadfast in their identity, letting guests know that Lom Wong is simply not who they have ever been, nor is it what the restaurant will ever become.
Like Taan, Lom Wong turned to social media to clearly set expectations before guests even walked 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 rooted in authenticity. Sunny Martin serves as the guiding light of cultural context for the restaurant, constantly advising the team on whether changing a single element of a dish would fundamentally compromise its integrity. For instance, while a mango salad can be ordered with shrimp served safely on the side, the kitchen will steadfastly refuse to remove beef or shrimp paste from dishes where those ingredients are a necessary component.
Chayaluk takes a similarly thoughtful, balanced approach at Taan. Rather than leaving dietary restrictions entirely unaddressed, the restaurant always features a dedicated vegan and gluten-free option—currently a fried rice dish—which Chayaluk describes as a catchall solution for diners who cannot consume other items on the menu. She ensures that this particular dish is executed with care, noting that it is crafted to be genuinely delicious and substantial rather than treated as a mere appetizer or a lazy afterthought.
Behind these policies is a shared philosophy that boundaries are vital for the health of the business. Staff members at both Taan and Lom Wong are actively encouraged by their leadership to uphold these operational lines. Both Chayaluk and Martin emphasize that these boundaries are just as important for protecting their kitchen and front-of-house staff’s peace of mind as they are for ensuring proper quality control for the diners.
While enforcing these limits has naturally generated some minor backlash, the proactive expectation-setting—both at the start of the meal and beforehand through transparent social media communication—has for the most part been received well by the public. When addressing guests who request disallowed modifications, the staff relies on a polite, transparent approach. As Martin describes it, the conversation involves kindly explaining to guests that the kitchen respects their personal preferences, but gently reminding them that those preferences belong strictly to them, while steering them toward alternative dishes on the menu that already naturally align with those dietary needs.
