Step off the train at the Capistrano Depot on a Saturday morning and the old habit kicks in automatically. Cross the tracks, walk the short stretch of Los Rios Street past the Montanez, Rios, and Silvas adobes, the three original structures left from California's oldest residential neighborhood, grab a scone at The Tea House on Los Rios, maybe let the kids feed a goat at Zoomars, and head back to the car within the hour. That was the whole visit. Los Rios was a nice detour, not a destination you'd build a day around.
That habit no longer matches what's actually there. Directly across the street from Zoomars sits River Street Marketplace, a $70 million, 60,000-square-foot development that opened in late 2024 with close to 30 tenants. The historic side of the block didn't get bigger. The new side simply showed up next to it, and residents who used to treat Los Rios as a quick stop are now treating it as a full afternoon that runs straight into evening, without ever moving the car.
The Walk That Used to Dead-End
For most of its recent history, the Los Rios Historic District offered a small, fixed set of businesses open to the public. The Metrolink guide to the area lists three: Ramos House Cafe, The Tea House on Los Rios, and the O'Neill Museum, which doubles as the headquarters of the San Juan Capistrano Historical Society. Add Zoomars at River Street Ranch, the petting zoo and mini-train at 31791 Los Rios Street that's been letting kids feed alpacas and llamas for years, and El Adobe de Capistrano, the restaurant housed at the historic train depot, and that's close to the entire commercial footprint of the oldest neighborhood in the state.
None of that changed. The forty homes that make up the district, most of them private residences dating to the late 1700s through the early 1900s, are still there. The adobes are still there. Zoomars still runs weekday and weekend hours from 10 a.m. to 4 p.m., last entry at 3:30, feed basket extra. What changed is what sits across the street from all of it.
What Showed Up on the Other Side of Paseo Adelanto
The San Juan Capistrano City Council approved the River Street Marketplace project back in 2019. Almquist, the development firm led by Dan Almquist, purchased the land from Ito Nursery and broke ground in early 2022. Roughly three years later, the marketplace opened with a tenant list that reads nothing like the historic side of the street: Free People, Tecovas, Wildfire Mercantile, La Vaquera, Finca by David Pratt, CAPO Leisure House, Mendocino Farms, McConnell's Fine Ice Cream, and a small food hall called Rodeo River Street with concepts including Parana Empanadas, Kebab Craft, NOM, Bred Hot Chicken, and Kozan Teahouse.
La Vaquera, the marketplace's flagship restaurant, is led by executive chef Aaron Zimmer and was created by Acme Hospitality, serving ranchero-inspired, wood-fired dishes from an indoor bar and dining room that opens onto a covered patio with fire pits. Finca by David Pratt takes a similar wood-fired approach, drawing its menu from Mexico's influence on early California and dressing the room to match. CAPO Leisure House, run by Capistrano Brewing Co., anchors the drinking side of the development with a 40-foot bar, its own fire pit, and retractable doors that turn the whole space indoor-outdoor on a warm night. Wildfire Mercantile, a Western goods shop owned by Troy and Susan Stansbury, moved into the bigger River Street space after already running a smaller storefront on Old Mission Road, a detail that says something about how much demand was already sitting nearby waiting for room to grow.
The Zoo Didn't Move. It Just Got a New Neighbor
The detail that makes this worth mapping out, rather than just listing, is the geography. Zoomars sits close enough to River Street Marketplace that the ranch's own site describes itself as conveniently located across from it. That means a petting zoo that predates the marketplace by years, running on the same $8 feed baskets and pony rides it always has, now operates directly across the street from a brewery with a 40-foot bar and a restaurant helmed by a named executive chef. Nobody built a connector or a plaza to link the two sides. They're just close, separated by little more than a street, which is exactly what makes it possible to treat them as one outing instead of two separate trips on two separate weekends.
How the Day Actually Splits
The practical effect shows up in what's open when. The historic side runs on daytime hours. Zoomars closes at 4. The Tea House serves lunch and weekend brunch, not dinner. That leaves the back half of the day, from late afternoon through evening, almost entirely to the marketplace side, where restaurants like La Vaquera and Finca are built for dinner service and CAPO Leisure House is built to keep the lights on after the historic cottages have gone quiet.
| Time of day | Where locals end up | Why |
|---|---|---|
| Morning | Ramos House Cafe or The Tea House on Los Rios | The historic-side cafes open first, and Zoomars opens at 10 for the train ride and feeding pens |
| Midday | Rodeo River Street food hall | Fast-casual concepts like Parana Empanadas and Kebab Craft handle a quick lunch better than anything on the historic side |
| Shopping window | River Street Marketplace boutiques | Free People, Tecovas, and Wildfire Mercantile sit just across the street from the adobes |
| Dinner | La Vaquera or Finca by David Pratt | Both opened with the marketplace, both built as sit-down rooms |
| Evening | CAPO Leisure House | The one spot in the immediate area still running a fire pit and full bar after the historic side has closed for the day |
Read that table as a single day rather than five separate errands, and the shape of it makes sense. Morning and early afternoon belong to the 250-year-old side of the street. Late afternoon through evening belongs to the side that isn't even two years old. The train depot sits at the hinge point, which means a resident who parks once near the Capistrano Depot, or arrives by Metrolink, can move through the entire sequence without moving a car until it's time to drive home.
Why This Is Worth Knowing Now
The version of Los Rios that existed before late 2024 was a place you visited for an hour and left. The version that exists now, with a full-service restaurant scene, a craft brewery, and a boutique row sitting a short walk from the oldest surviving adobes in California, supports something closer to a full day. That's a genuinely different neighborhood to live near, whether the plan is a Saturday with out-of-town guests who want to see the Mission-era buildings before dinner, or just a weeknight where the historic side handles the afternoon and the marketplace handles everything after 5.
None of this required anyone to renovate the adobes or expand the petting zoo. It required a developer to build 60,000 square feet of restaurants and shops close enough to walk to, and it required nobody removing what was already there. The result is a stretch of San Juan Capistrano where two very different economic eras sit across a two-lane street from each other, both open for business, both worth the walk.
