If you sent an out-of-town cousin to Wai Kai this summer and told them to grab dinner at Kitchen Door Napa, they walked into a restaurant that doesn't exist anymore. It closed. The name on the building changed. The kitchen changed. Even the ground floor got renamed. And if you Google around for "what's new at Wai Kai," you'll still find plenty of pages describing the old lineup like it's current, because the internet is slow to catch up to a neighborhood that keeps rewriting itself.
Ewa Beach's food scene has been having a real moment lately, between DOMODOMO's arrival at 360° Ewa Beach Country Club a couple miles inland and the ongoing churn at Wai Kai itself. This piece is about Wai Kai specifically, because that's the part most residents interact with weekly, and it's the part where the gap between what's written online and what's actually happening has gotten the widest.
The Restaurant Everyone Still Thinks Is There
Kitchen Door Napa opened at Wai Kai in 2023, a two-story, 7,200-square-foot dual concept from Michelin-recognized chef Todd Humphries, split between the upstairs Plaza Grill and the downstairs Boardwalk Cafe. It was a genuine anchor for the property, the kind of restaurant that gets written up in Honolulu Magazine with quotes about regulars and locals discovering it for the first time. For a couple of years, if you asked anyone what to eat at Wai Kai, this was the answer.
That answer is now wrong. The upstairs space that housed Plaza Grill closed, and something else moved in.
Who's Cooking Upstairs Now
Hali'a by Side Street Inn opened in that upstairs space in August 2025. The team behind it isn't new to Oʻahu's restaurant scene. Cheryl DeAngelo and Lisa Meyer run the original Side Street Inn on Hopaka Street and Side Street Inn on Da Strip, two of the more enduring names in local comfort food, and Fred DeAngelo runs the kitchen at the new Wai Kai location. Kelly Grady, the general manager, told KHON2 what the goal was:
"We are excited to bring the famous Side Street Inn style of ono, family-style service with local comfort food to the west side."
That's a meaningfully different restaurant from what came before it. Kitchen Door leaned into California wine country by way of Napa. Hali'a leans into a menu style that's been a Honolulu staple for decades, now transplanted to the leeward side.
The Downstairs Café Got a New Name Too
The change wasn't limited to the upstairs dining room. The Boardwalk Café on the ground floor was rebranded Sidewalk Café, and it now operates under the same ownership as Hali'a upstairs. That's a small detail with a practical payoff for anyone with kids: a family doing lagoon activities can grab quick bentos and burgers downstairs while the adults get a full sit-down meal one flight up, all under one operator instead of two separate businesses that don't coordinate.
Seafood specials were still being worked out as of the summer opening, so the menu upstairs is not fully settled yet. If you're planning a specific dish around a visit, it's worth checking the board that week rather than assuming it matches what you saw a month ago.
The Lagoon Got Taller
The 52-acre Wai Kai Lagoon and the Wai Kai Wave, Hawaii's stationary deep-water surf wave, have been open since 2023, and that part of the property hasn't changed in concept. What did change is the addition of Wai Kai AquaPeakz, an elevated obstacle course and slide tower built onto the existing floating playground, along with the Leeward Launcherz, a set of suspended floating bridges strung between platforms. If the last time you were on the water here was a year or two ago, there's now more to climb and cross than there used to be.
The Rules Changed With It
For 2026, Wai Kai also adjusted its ticketing around age and weight, which matters if you're planning a visit around younger kids. Here's what's currently in place:
- Lagoon activities require keiki to be at least 6 years old and at least 30 pounds
- The wave pool requires a minimum age of 10 and a minimum weight of 80 pounds
- Keiki under 13 need a parent or guardian present at the wave pool
- The Keiki Course on the lagoon is built for ages 4 to 6
- The Aloha Course is open to ages 7 and up
None of this is dramatic, but it's the kind of detail that ruins an afternoon if you show up with a five-year-old expecting them to ride the wave pool and find out at the ticket counter that they can't.
Thursday Is Still the Move
Some things at Wai Kai haven't changed, and the Thursday rhythm is one of them. The Ono Grindz and Makeke farmers market runs every Thursday from 4 to 8 p.m. at 91-1621 Keoneula Boulevard, with more than 50 food and craft vendors rotating through. Admission and parking are both free, and it's pet-friendly, which on the west side counts for something. One of the vendors worth knowing by name is Uncle M's Smashburgers, started by a James Campbell High School senior whose crew is made up of friends from school and church. It's the kind of small business story that doesn't show up in a corporate press release but sticks with you after you've eaten there once.
Pair the market with the free Thursday Night Surf Show at 7 p.m. and you've got a full evening without leaving the property. Dinner upstairs at Hali'a, a walk through the market vendors, then down to the wave deck to watch the show as the sun starts to drop. It's an easy loop, and it's one that didn't exist in this exact form a year ago.
Why This Is Worth Knowing Even If You're Not Going Out to Eat
None of this is really about restaurants. It's about how fast a place like Wai Kai can rewrite itself while the search results describing it stay frozen in an earlier version. A neighborhood amenity that swaps its anchor tenant, adds a new attraction, and changes its ticketing rules within twelve months is a neighborhood that's still actively being built out, not one that's finished. That's useful context whether you're deciding where to eat this week or just trying to understand what kind of community you're actually part of right now.
If you want a version of this that gets updated as things change rather than left to go stale online, that's the kind of local read Tia Perez puts together for the Hoakalei and greater Ewa Beach area. Reach out anytime you want the current picture of what's happening on this side of the island, whether that's a restaurant swap at Wai Kai or a straight answer about the market when you're ready for one.
