If you live on the Eastside, you already know 17th Street. You have your Wild Goose seat, your Sidecar order, your Hi-Time bottle. What has shifted this year is harder to see from the sidewalk. The most interesting rooms that opened in and around Eastside Costa Mesa in 2026 are tucked inside other rooms, behind roll-up doors, or hiding on a side street off the main strip. The map hasn't grown outward. It has grown inward.
That is the thesis worth holding onto as the summer settles in: the Eastside's food scene this year is a scene of tenants inside tenants, day concepts flipping into night concepts, and small counters where reservations move faster than reviews. If you want to actually eat somewhere new nearby, the addresses you already walk past are doing more work than the ones with fresh signage.
The Day-Into-Night Flip
The clearest example sits at 120 Virginia Place, a block off 17th. By day it is Hola Adios, the craft coffee shop locals have used as a working spot for a while. Wednesday through Saturday after 5 p.m., the same room becomes Diner Noche, a beef-tallow-fried smash-burger operation from owner Ryan Jimenez. Orange Coast's April 2026 rundown priced the menu at $10 for smash burgers and fried chicken sandos, $6 for fried pickles, and $14 to $16 for New Jersey-style disco fries topped with chorizo or carnitas. The specialty nachos land at $15.
This is not a pop-up in the loose sense. It is the same kitchen, same address, different concept after dark. For an Eastside resident, the practical read is that you gained a dinner option in a building you were already using for coffee, without a new lease or a new parking pattern. If you tried the room in 2025 and stopped paying attention, the room now does something else three nights a week.
Around the corner on Virginia and up the 17th Street corridor, the same theme repeats.
Behind Unmarked Doors
Two of 2026's most talked-about additions are effectively hidden.
Gremlin Garage is a coffee speakeasy behind a roll-up garage door, described by Travel Costa Mesa as a woman-owned spot with espresso and creative drinks in what looks, from the street, like a garage. That is the entire point. It sits off the standard 17th Street pedestrian flow, which is why it has been able to stay a locals' cue rather than a weekend line.
Highball and Naisho Omakase debuted in Costa Mesa on March 23, 2026, adjacent to each other. Highball is a Japanese-style bar built around the "authentic bar" tradition, where a whisky highball is treated as a discipline of ice, dilution, and balance rather than a house cocktail. Naisho is a 14-seat omakase counter led by co-founders Thomas Pham and Andrew Le, with Chef Shimpei Shinohara on the counter and Justin Oh and Tony Morabito behind the bar. Fourteen seats is the number to remember. A room that small books on word of mouth before it books on search, which is why your neighbor got in and you did not.
The pattern across all three: the interesting new rooms in 2026 are small, quiet from the street, and easier to miss than to find. If the door looks like a garage or a side entrance to another business, that is probably where you are supposed to be.
The Strip Itself Is Stable
While the new rooms are hiding, the visible 17th Street lineup has barely moved. That is worth naming, because it means the map you memorized still works for most weeknights.
- Wild Goose Tavern and Eat Chow anchor the sit-down casual end
- The Crack Shack, Richard Blais's fried chicken spot, holds the quick-lunch slot
- Plums Café still runs the long-standing brunch queue
- Sidecar Doughnuts and Hi-Time Wine Cellars are the two names most out-of-town guests will ask about by name
- Oak & Coal covers charcoal-grilled Japanese for larger groups
- Tres Muchachos Wine Bar & Kitchen does all-day brunch with a seafood tilt
- 'Ai Pono Cafe and Jan's Health Bar handle the fast-casual middle
- Stella Jean's shares space with Pop Pie Co., which is a dinner-and-dessert combo more useful than most people give it credit for
- The Straw covers the retro milkshake corner
The retail spine reads the same way. Factory Records is still the vinyl stop, with the store leaning into punk, rare jazz and soul, and releases from local label Ubiquity. Almond Surfboards, Mama Bijoux (Katie Miller's jewelry atelier), Rococo Boutique, and Covry Eyewear are all where you left them.
Over at Paseo 17, the courtyard center on 17th, Milligram's kitchen is under a spring 2026 upgrade, with the rest of the shops and restaurants open through the work. Milligram's Saturday Brunch Club with a live DJ is still running from 11 a.m. to 3 p.m., with patio reservations on OpenTable.
The Country Club Closed. That Actually Matters.
The one visible subtraction is The Country Club, the restored 1950s-style room on 17th that ran live music, DJs, and dancing after hours. It has closed. Its own farewell note points guests to its sister rooms, Playa Mesa and Wild Goose, both on 17th Street.
For an Eastside resident, this is the most consequential change of the year, and it is not a food story. It is a late-night story. The Country Club was one of the few rooms on the Eastside where a dinner could turn into a dance floor without moving your car. Its exit is why the new arrivals matter more than they otherwise would. Highball and Naisho are not replacing that energy. They are a quieter, seated version of a night out. If you were relying on The Country Club as your default post-9 p.m. move, your default has changed.
And One More Address Worth Knowing
Slightly outside the Eastside proper but close enough that most residents will use it, Pacific Pearl Cafe opened its second location at The Met, 575 Anton Boulevard, on January 26, 2026, with a grand opening on January 30. It is a breakfast-and-lunch operation from Chef Michael Campbell, whose first location is in San Juan Capistrano. Hours are 7 a.m. to 2 p.m., Monday through Friday. If your work rhythm sends you toward South Coast Metro during the week, this is the addition to file away.
The other one further west, Earlybird Breakfast Burritos, opened at 2930 Bristol Street on January 17, 2026. Not Eastside, but a short drive if you are already going that direction.
The Summer 2026 Backdrop
Two calendar items shape how the Eastside actually feels this month.
The OC Fair runs July 17 through August 16 for its 136th edition, dark on Mondays and Tuesdays. The number that changed this year is the attendance cap: 55,000 people daily, with tickets required in advance. General admission is $13 on Wednesday and Thursday, $15 Friday through Sunday, and $9 for seniors 60 and up and kids 6 to 12, with kids 5 and under free. For Eastside residents, the practical effect is that Fair Drive traffic and the surrounding streets behave more predictably than in past summers, because same-day walk-ups are no longer part of the equation. If you have been treating July as a stay-in-the-neighborhood month, the cap is quietly on your side.
Two park projects that have shaped daily routines all year are finally closing out. TeWinkle Park is finishing a major lake repair, with a new liner, water-quality upgrades, landscaping, and shoreline rebuilding, with the city listing a summer 2026 end date. Ketchum-Libolt Park improvements started the week of January 5, 2026, and are expected to wrap in late summer. Runners and dog walkers who have been routing around both since winter get their routes back at roughly the same moment the Fair lets out.
Reading the Year So Far
Put the pieces next to each other and the shape of the Eastside in 2026 is coherent. The 17th Street strip is a settled asset. The new energy is landing inside existing addresses, in small rooms, and in places you would not find on a first walk. One late-night anchor is gone, and the rooms replacing that energy are quieter and smaller by design. The summer around all of it is more capped, more predictable, and more park-friendly than it has been in a while.
That combination, more than any single opening, is the thing to know about eating and moving around the neighborhood right now.
If your rhythm on the Eastside is shifting with the map, or if you have been thinking about how a home on this side of Costa Mesa fits the way you actually spend a Saturday, the team at Cadence Real Estate is happy to talk it through. Let's Get Started.
