Knife Pleat

The Verdict

If you're weighing Knife Pleat against Mastro's Ocean Club for a special occasion in Costa Mesa, the decision comes down to format: Mastro's delivers a familiar steakhouse celebration; Knife Pleat delivers something harder to find at this price point in Orange County; Michelin-starred French precision with genuine seasonal intention. For a date night, anniversary, or client dinner where the food needs to match the occasion, Knife Pleat is the stronger call.

Knife Pleat holds a Michelin 1 Star (retained through 2025) and ranked #20 on the LA Times 101 Best Restaurants 2024. At $$$$, it is one of the most credentialed restaurants in Southern California outside of Los Angeles proper.

The Restaurant

Knife Pleat sits in the Penthouse level of South Coast Plaza in Costa Mesa, a retail address that sounds unlikely for serious dining, but works entirely in context. The room has tall curved columns, soft lighting, plush purple banquettes. The atmosphere is calm and cocooning: low ambient noise, unhurried pacing, enough physical separation between tables to make conversation easy. For a business dinner or a celebration that requires privacy and a grown-up atmosphere without the aggression of a loud brasserie, this room delivers. It reads closer to the quieter end of fine dining in Le Bernardin territory than to the theatrical energy of something like Alinea.

Chef Tony Esnault trained in fine-dining kitchens in France before leading kitchens in New York and Los Angeles. Restaurateur Yassmin Sarmadi co-runs the operation, her influence is visible in one of the restaurant's most distinctive offerings: an annual Nowruz dinner inspired and overseen by Sarmadi's mother, Shamsi Katebi. That dinner is worth tracking if you're planning ahead, it represents the kind of calendar-specific event that doesn't exist elsewhere in this dining category in Southern California.

What to Order and When to Visit

The menu format is the first thing to understand. Knife Pleat runs seasonal four- and six-course dinners, a three-course lunch, a Saturday afternoon tea. The seasonal rotation is not incidental, it is the core of Esnault's cooking philosophy, it directly affects what you should book and when.

The légumes de saison on the Flora vegetable-forward menu is consistently cited as Esnault's most compelling dish. Individual vegetables, radish, snap peas, carrots in multiple colors, green onion, celery, broccolini, are each cooked by the method that suits them leading: roasted, braised, steamed, or left raw. The result is a dish where the cooking technique serves the ingredient rather than the other way around. If you are visiting when this is on the menu, order it.

Other dishes that appear in verified coverage: pearl barley prepared to mimic risotto under a sunflower foam with chanterelles; duck breast with skin-on precision plating alongside charred corn relish. These are seasonal preparations, which means availability depends on timing. The six-course dinner format gives you more exposure to what Esnault is doing across the current seasonal arc, if you are making the trip specifically for the food, the longer format is worth the additional spend.

The Saturday afternoon tea is a practical point worth flagging: it is a lower price-of-entry option for first-timers who want to experience the room and the kitchen's sensibility before committing to a full dinner booking. Compared to Single Thread Farm in Healdsburg or The French Laundry in Napa, which have no mid-tier entry point, Knife Pleat's tea service is an accessible way in.

For seasonal planning: the Nowruz dinner (Persian New Year, typically mid-March) is a one-off annual event and books fast. If that falls in your window, prioritise it over a standard dinner booking.

Booking

Booking difficulty is rated Hard. Book a minimum of three to four weeks out for a standard dinner reservation. For the Nowruz dinner or peak weekend slots, plan further ahead. The Saturday tea service may have more availability than weekend dinner, but don't assume walk-in flexibility. Check the reservation system directly for current lead times.

Practical Details

How It Compares

In the contemporary fine-dining tier in Southern California, Knife Pleat competes most directly with venues like Jungsik and César in terms of format and price positioning, seasonal tasting menus with a clear culinary point of view, in rooms designed for extended dining. Within Costa Mesa specifically, the comparison set is narrower. Hana re at $$$$ is the only direct price-tier peer locally, but it is omakase Japanese rather than French, the experience is more intimate and counter-focused. If you want a full room with a conventional table service format at the top of the local market, Knife Pleat is the option.

Vaca at $$$ is the most sensible alternative if budget is a consideration. It is Spanish rather than French, less formal, better suited to groups who want a lively room rather than a quiet one. ANQI sits at a lower price point with Asian Fusion positioning, a reasonable choice for a casual dinner in a well-designed room, but not a substitute for what Knife Pleat is doing technically. Mastro's Ocean Club is the default choice for expense-account seafood in Costa Mesa, but it is a reliable rather than distinctive option. If the occasion warrants spending at this level, Knife Pleat's Michelin credential and seasonal menu give you more to talk about at the table. Sidecar Doughnuts and Coffee is not a competitor in format or price, it is worth knowing as a breakfast option before or after time in the area, not a dinner alternative.

Against the broader California fine-dining reference points, Lazy Bear in San Francisco, The French Laundry in Napa, Emeril's in New Orleans, Knife Pleat is a genuinely credentialed option that happens to sit in a shopping centre rather than a destination neighbourhood. Don't let the address discount the food.
