For five years, the largest storefront in Traville Village Center sat dark. The space at 9755 Traville Gateway Drive had been Nantucket's Reef until 2020, and then it was nothing at all: a papered window at the front of a shopping center that otherwise held one of the busiest Giant grocery stores in the area, a Cava Mezze that always seemed full, and a Black Lion Cafe with a line out the door on Saturdays. The center worked, but it worked with a hole in the middle of it.
That hole closed in May. If you live in North Potomac, that is the single most useful thing to know about your summer.
The Slot That Sat Dark for Five Years
El Patio Argentine Restaurant opened its Traville Village location on Thursday, May 14, 2026, taking over the former Nantucket's Reef footprint that had been vacant since 2020, according to Patch's Rockville coverage. The restaurant is the second location of a family-owned Argentine kitchen that first opened on Twinbrook Parkway in 2001 and has spent the last two decades at 5240 Randolph Road in Loehmann's Plaza, per The MoCo Show.
The menu is what it has been at Randolph Road for years: empanadas, milanesas, house-made chorizos, parrillada-style grilled meats, and a bakery-and-market counter tucked behind the dining room with imported goods and what the restaurant itself calls the largest Argentine wine selection in the metropolitan area. Store Reporter noted the second-location debut this week at 9755 Traville Gateway Drive, the onetime Nantucket's Reef space that had been empty since 2020.
The address matters more than the menu here. A shopping center anchored by a full grocery, a coffee shop, a Mediterranean sit-down, and a sushi counter had been operating with its largest tenant missing. That configuration is now complete.
What Traville Village Now Holds
The center sits at 9700 Traville Gateway Drive, a short drive from the Universities at Shady Grove and inside what the North Potomac Citizens Association describes as one of four shopping centers ringing the neighborhood. Its current tenant mix, block by block, reads like a completed grid:
- Giant Food for the weekly grocery run
- Cava Mezze for the sit-down Mediterranean dinner that runs later than most of the pad restaurants in the area
- El Patio for the family-style Argentine grill night, plus a walk-in bakery counter and imported pantry
- Black Lion Cafe for morning coffee and pastry
- Sushi Oishii for the takeout sushi order
- Dunkin' for the drive-through coffee
Take any weeknight errand a household in the Traville, Quince Orchard, or Dufief neighborhoods actually runs, and it is now covered inside a single parking lot. That was not true in April.
Why This Changes a Weeknight
North Potomac has never lacked restaurants. It has lacked a place where you could pick up dinner, buy groceries, and end up with something other than fast casual, all in one stop. Potomac Village Deli and Quincy's have their following. So do the shops along Darnestown Road. But the geography meant most residents were driving to Kentlands, King Farm, or the Pike for anything that could be called a sit-down evening with the family.
The El Patio opening quietly shortens that trip. Bethesda Today noted the restaurant sits alongside the team's broader growth in the county, and separately reported that Maurizio's is expected to open at 10120 River Road in the former Renato's space this summer, from the group behind Cava Mezze in Rockville and Julii, Melina, and Bouboulina at Pike & Rose. For North Potomac residents, that means two upscale, chef-driven suburban openings landed within a fifteen-minute radius in the same summer, both of them replacing spaces that had been closed for years.
The practical effect: the standard weekday pattern of "we'll grab something on the way home" now has an option that is not a national chain and not a thirty-minute drive.
The Outdoor Counterweight
Traville Village is the indoor anchor. The outdoor one, for anybody who has lived here more than a season, is the Muddy Branch Greenway Trail. Montgomery Parks lists it as nine miles of natural surface through Muddy Branch Stream Valley Park and Blockhouse Point Conservation Park, crossing rocky upland forest, streambanks, and meadows on its way from Darnestown Road down to the C&O Canal. AllTrails maps the full experience closer to 12.5 miles with about 705 feet of elevation gain, reflecting the fact that most people who use the trail piece it together in segments rather than as a through-hike.
The two most useful trailheads for a North Potomac resident sit at opposite ends of the neighborhood. One is at the intersection of Turkey Foot Road and Query Mill Road, per AllTrails, which drops you onto the northern segment. The other is the large parking lot at Blockhouse Point Conservation Park on River Road, which Montgomery Parks flags as the primary access for the southern half and the new bridge crossing to Pennyfield Lock on the C&O Canal, per the Muddy Branch Alliance. The trail passes the Potomac Horse Center along the way, which is why you will pass more equestrian traffic than most suburban trails.
For a summer routine, this matters because the trail is long enough that residents can use different segments for different purposes: a short morning loop from Turkey Foot before work, a longer weekend push from Blockhouse Point to the canal, an early-evening dog walk in the woods rather than on a sidewalk. The Muddy Branch Alliance emphasizes that the trail is shared by hikers, mountain bikers, and equestrians, so segment choice is more consequential than on a flat rail-trail.
Where Traville Sits Among North Potomac's Other Anchors
The North Potomac Citizens Association names four shopping centers that ring the neighborhood. It is worth seeing them side by side, because the case for Traville Village as the new default is really a case about what the other three do and do not offer.
| Center | What it does well | What it does not cover |
|---|---|---|
| Traville Village Center | Full grocery, sit-down dinner, coffee, sushi, imported market | — |
| Potomac Oak Center | Convenience, quick errands | Sit-down dinner |
| The Shops at Potomac Valley | Neighborhood services | Full grocery, dinner anchor |
| Travilah Square | Everyday retail | Sit-down dinner anchor |
That is not a knock on the other three. It is an argument that the household weeknight, the one that includes groceries and dinner and a coffee stop, now has one obvious answer instead of a two-stop workaround.
A Usable Summer Week
If you are trying to actually put this into a rhythm before Labor Day, the shape looks like this:
- Monday or Tuesday grocery run at Giant, with the option to add a bakery stop at El Patio's back counter for facturas and pantry goods you would otherwise have to drive to a specialty market for.
- A midweek family dinner at El Patio, which the restaurant itself positions as casual and family-style, so it holds up for a weeknight rather than requiring the reservation choreography of a weekend spot.
- A weekend morning at Black Lion Cafe before a Muddy Branch segment, either the Turkey Foot–Query Mill approach for a short loop or the Blockhouse Point lot on River Road for a longer stretch toward Pennyfield Lock.
- A Sunday sushi pickup from Sushi Oishii to close the week without touching the stove.
- A summer trip out to 10120 River Road once Maurizio's opens, if you want to test whether the Cava Mezze team's Italian concept lives up to the reputation of their North Bethesda restaurants.
That is not a highlight reel. It is what a full week actually looks like now that the center block is complete.
The One-Sentence Version
North Potomac has always been quiet, wooded, and slightly inconvenient by design. The neighborhood traded density for lot size and trail access, and residents who chose it knew the tradeoff. What has changed this summer is a small correction inside that tradeoff: the largest empty storefront in the neighborhood's most useful shopping center is no longer empty, and the trail system it counterweights has never been better mapped or better bridged. For the household that already lives here, the summer of 2026 is less about deciding where to go and more about noticing that the ordinary options finally line up.
