    After graduating from Evergreen State College, Gillian’s love of travel drove her to buy an around-the-world ticket to explore the globe before settling into a career in journalism. That was promptly stalled after her first stop in Hawaii, where the week turned in a 3-month stay and included her first job in a restaurant. She fell in love with the fast-paced, multi-faceted work that the restaurant business had to offer, and she’s been working in the industry in various capacities ever since.

    Gillian joined the El Gaucho Portland team in 2012, and served as the Wine Captain until her promotion to General Manager. Growing up in Portland, Gillian loves to explore the local wine region and keep up on the local restaurant scene with her husband, Joe. Among other hobbies, she loves to cook, organize, make tiny little appetizers, host dinner parties, and hang with her Chocolate lab-Chesapeake bay retriever, Baila.

    El Gaucho Event’s Executive Chef Steve Cain fell in love with his craft at an early age while watching relatives prepare lavish holiday feasts at their family beach house in Olympia, WA. Growing up with a mother who was a chef further inspired him to make cooking not only his passion, but his trade. With no formal training but 30 years of experience, Chef Cain moved to Seattle to work at Henry’s Off Broadway under Chef Bruce Bonholzer, who attended Le Cordon Bleu in Paris. This experience would be a turning point in his career and taught him that with great food comes lasting memories.

    Cain continued to work in a select group of Pacific Northwest restaurants, honing and burnishing his culinary skills. For 8 years he worked as Executive Chef at Waterfront Seafood Grill (now AQUA by El Gaucho) and when the Mackays opened their first eastside venture in November 2008, El Gaucho Bellevue, Steve was given the position of Chef de Cuisine. After nearly 4 years of helping create the menu on the eastside, Cain returned to his roots within the company as Executive Chef of AQUA by El Gaucho. As the offsite program, El Gaucho Events, began to grow, Cain stepped in to the roll of El Gaucho Events Executive Chef in 2013. In April of 2014, Cain became Executive Chef at El Gaucho Portland.
