“Chef Jill Arreguin never set out to collect accomplishments. She spent a lifetime collecting lessons—and every one of them found its way into her kitchen.

Her journey began on a family farm in the American Midwest, where meals followed the seasons and nearly everything on the table was grown, raised or preserved by hand. Before winter, the family gathered to butcher livestock that would sustain them through the colder months, while trips to the grocery store were carefully planned and infrequent.

Jill learned early that memorable food wasn't about abundance. It was about resourcefulness, respect for every ingredient and the importance of the people gathered around the table.

Drawn to the kitchen from an early age, Jill began her culinary career in an upscale Irish restaurant, where she developed a classical foundation in whole-animal butchery, fish fabrication, traditional stocks and mother sauces, and the disciplined techniques of European cooking. The kitchen demanded precision, consistency and humility—principles that continue to shape her cooking today.

When Jill became a mother, she stepped away from restaurant kitchens in search of greater stability and more time with her young son. She built a successful career in technology and financial systems, including leadership roles with Microsoft and other global technology companies.

That career took her around the world, but food was never far away.

Wherever she traveled, Jill sought out markets, producers and professional kitchens, sometimes working alongside chefs for weeks and sometimes for a single service, learning their techniques and traditions firsthand. The dream of owning her own restaurant wasn't abandoned—it was simply waiting for the right season of life.

A Culinary Education Without Borders

As her travels expanded, so did Jill's culinary education.

In Newport, Rhode Island, she cooked for historic estates and private dinners. In northern Italy, she immersed herself in handmade pasta and discovered how extraordinary ingredients often call for the simplest preparation. In Rome, she learned traditional pasta by feel rather than recipe. In Goa, she explored spice farms and regional cooking shaped by centuries of Portuguese influence.

Along the way came Nordic seafood preservation, Scottish beef and whisky traditions, Argentine asado and whole-animal butchery in Mendoza, Baja seafood, and the deeply layered moles and chocolate traditions of Oaxaca.

Those experiences didn't lead Jill toward one particular cuisine. Instead, they shaped the way she cooks: classical technique, exceptional ingredients, respect for tradition and the confidence to let simplicity speak for itself.

That philosophy defines her seasonal, European-inspired cooking at King William today.

Where Food and Wine Meet

Wine became an equally important part of Jill's education.

She completed Court of Master Sommeliers theory, earned her WSET Level 2 certification in 2024 and continues her wine studies. Her personal cellar has grown to nearly 600 bottles, but for Jill, collecting wine has never been about accumulating labels.

It has always been about the table.

She approaches wine with the same curiosity she brings to cooking: How does a wine change a dish? How does food reveal something unexpected in a bottle? And how can the combination create an experience greater than either one on its own?

That philosophy now shapes the Champagne-first wine program at King William Wine Co.

Under Jill's direction, the growing cellar has expanded to more than 225 selections and more than 1,200 bottles, with particular depth in Champagne and the classic wine regions of Europe alongside benchmark producers from Napa Valley, South America, Australia, South Africa, Texas and beyond.

The collection ranges from grower and prestige Champagne to Grand Cru Burgundy, mature Bordeaux, Vega Sicilia, Dominus, Don Melchor and other celebrated estates. Alongside these collectible wines are smaller producers, unexpected discoveries and approachable bottles selected because Jill believes an exceptional wine experience should never depend solely on price.

New producers, vintages and Champagne selections continue to be added as the cellar evolves.

For Jill, the wine list isn't separate from the menu. It is another part of the same conversation.

A dish may suggest a particular wine. A remarkable bottle may inspire a dinner. Champagne can begin an evening, accompany caviar or remain at the table throughout the meal. Through Coravin reserve pours, special tastings, winemaker dinners and the Personal Wine Concierge, Jill's goal is to make wine both exciting for experienced collectors and approachable for someone discovering a new region or producer for the first time.

Food and wine are considered together from the beginning.

A Dream Realized in King William

After years spent learning in kitchens, traveling the world, studying wine and imagining the restaurant she might someday create, Jill found the place for that dream in San Antonio's historic King William District.

Together with her husband and business partner, Juan Arreguin, she created King William Wine Co. around a simple idea: exceptional food and exceptional wine should be accompanied by the kind of genuine hospitality that makes people feel cared for.

Today, Jill's kitchen is the culmination of a lifetime of experiences.

Her seasonal, European-inspired cuisine brings together classical technique, exceptional Texas ingredients and influences gathered from kitchens, markets, vineyards and tables around the world. Fresh seafood, house-made pastas, premium Texas steaks, caviar and dishes rooted in European traditions all reflect a cooking style that values restraint, seasonality and the integrity of the ingredient.

Her understanding of wine is woven into that same philosophy, creating a restaurant where food, wine and hospitality are considered together rather than separately.

But King William is not the end of Jill's culinary journey.

She continues to travel, taste, study and learn—bringing new ingredients, wines, traditions and ideas home to San Antonio while remaining grounded in the lessons that began at her family's table.

For Jill, cooking has never been about showcasing technique for its own sake. It is about making people feel welcomed and cared for, creating a table where they want to linger, and giving them a reason to return.

“After all these years, I've come to believe that people rarely remember every dish they ate. They remember how they felt around the table, who they shared it with, and whether they left wanting to come back. That's what I hope to give every guest who walks through our doors.”
