"This is a hungry neighborhood," Hosea Rosenberg told BizWest in June. He was talking about South Boulder, where he was getting ready to open Morso. "There's a lot of people in South Boulder, and I don't believe there are enough restaurants to support them."
The openings people kept talking about in 2026 came from chefs and owners who already had a following here. Each one moved into a restaurant space the city already had and rebuilt it around a gap the owner could name. Three of the four went into rooms tied to the owner's own business or to a friend's. Several also chose shorter menus.
If you're deciding where to spend a fall evening, the rooms come with good stories. Here's what opened, where, and what the people who run each place say to order.
South Boulder gets the red-sauce restaurant Rosenberg thought it lacked
Morso opened in late June at 627A S. Broadway, in the space that used to be Under the Sun. It's Rosenberg's first new Boulder concept since Santo opened in 2017, as 5280 noted in its fall roundup. He and his wife and partner, Lauren Feder Rosenberg, also run Blackbelly and Santo. They got the space through Kevin Daly of the Mountain Sun group. Rosenberg told BizWest that their friendship with Daly made the deal possible, and that the building came with a big kitchen and good parking.
The existing room shaped the menu. The Rosenbergs had been thinking about Spanish food, but the wood-burning pizza oven was already there, along with the hood system and walk-in cooler. "It just felt like a really smart and almost obvious move to do an Italian eatery here," Rosenberg told BizWest.
Most of the renovation work went into the dining room. Rosenberg called the old space "cavernous and dark." It now has an island bar, a private dining room behind a glass partition, and built-in banquettes. Several Boulder firms worked on it: Maliakai Architecture, Rachel B Interiors, Duggan Construction and Berger & Föhr Design.
What to order:
- Pizza. The dough is naturally fermented and builds on Blackbelly's bread program, which uses flour from Dry Storage in Boulder and Moxie Bread Co. in Louisville.
- The parms. The menu runs to Italian-American classics like chicken and eggplant parmigiana and linguine with clams. Rosenberg's Southwestern roots show up as Hatch green chiles on more than one pizza.
- Dessert. 5280 says to save room for the soft-serve, which you can order as an affogato.
Morso's website lists hours of 4 p.m. to close daily and links to online reservations.
North Boulder: a familiar room, a new French menu
Up at 4580 Broadway, Cinq à Sept opened in July in the space that had been Bellota and, before that, The North End at 4580 and Restaurant 4580. The owner is Bryan Dayton's Half-Eaten Cookie Hospitality Group, the team behind Oak at Fourteenth, Corrida and C Burger. According to 5280, the Boulder Bellota closed in January. That means North Boulder got its new French menu in a room that had been empty only a few months.
Dayton told Boulder Reporting Lab that the goal was a restaurant North Boulder residents would want, one that could also bring in diners from the rest of the city. The answer was to lean on chef Sam McCandless's background in French cooking.
The menu is deliberately short. "The menu's delicious, but it is definitely nice and tight and executed well," Dayton told Boulder Reporting Lab, adding that the smaller kitchen was part of the reason. Produce comes from Esoterra Farms, which supplies greens, carrots, squash and zucchini. Beef and lamb come from Buckner Family Ranch. The menu will change with the seasons, while a set of staples stays put.
Dayton's own order for a first visit:
- The bread and the oysters from Prince Edward Island
- The zucchini, which he called "next-level"
- The simple Esoterra salad
- The chicken, and probably the sole with brown butter and capers
The name means "five to seven," the French phrase for early-evening drinks. Dayton said diners are coming in all evening, not just for happy hour. As of Boulder Reporting Lab's October story, Cinq à Sept is open 4 to 9 p.m. Sunday through Thursday and 4 to 10 p.m. Friday and Saturday, with happy hour from 4 to 5 p.m. daily.
Downtown: Edwin Zoe changes concepts in his own space
San San works the same way, only closer to the Pearl Street Mall. Edwin Zoe, who runs Zoe Ma Ma and Pearl Poké, closed Dragonfly Noodle at 2014 10th St. and soft-launched San San there on August 4, the Daily Camera reported. 5280's fall roundup dates the restaurant's debut to July. Dragonfly started early in the pandemic as a counter-service spot with a limited menu, even though the room was designed for full service. Zoe told the Camera that San San is how he plans to "realize the full potential of the space."
The gap he named was specific. "What is glaringly absent, especially downtown, is that there isn't a Chinese place that you can go" for a special occasion, he told the Camera. He mentioned anniversaries as an example. San San serves American Chinese food in an 80-seat dining room with booths, outdoor tables, and cocktails from beverage director Matthew Jansen.
The name San San means "three mountains." Zoe told the Camera it comes from his first morning in Boulder more than 40 years ago, when he arrived as an incoming CU Boulder student and woke up to mist drifting over the first three Flatirons.
San San also has a short menu. Old-school Chinese menus often run 20 pages. San San planned about eight seasonal entrées, a half-dozen appetizers, a couple of soups, and a multi-course tasting menu for $40 to $50. The chop suey rotates with the seasons. On Friday nights Zoe roasts a single USDA prime rib, served until it sells out. There's also a homestyle burger, which Zoe connects to early Chinese restaurants in the American West, which often served burgers and meatloaf to stay in business.
Two things worth knowing before you go. Happy hour is progressive: from 3 to 4 p.m. selected items are $3, from 4 to 5 p.m. they're $4, and from 5 to 6 p.m. they're $5. The list includes dumplings, pulled pork bao, spicy cucumber, Sapporo draft and house wine. San San also doesn't take tips. Every bill carries an automatic 18% service fee, and nobody will ask you to add more. At opening, the Camera listed hours of 11:30 a.m. to 9 p.m. daily. sansan.food has the current schedule.
Baseline Road: an underused upstairs becomes a sushi bar
Temaki Joint is the one opening led by a chef new to Boulder. Duy Pham spent decades in Denver-area kitchens, including Opal, Parker Garage, Foraged and Hana Matsuri's Glendale location. The space itself follows the same pattern as the others. His business partner owns the building on Baseline near U.S. 36 and felt the upstairs wasn't being used to its potential, Boulder Reporting Lab reported.
Temaki Joint started as a trial sharing space with Tea Mate. Pham then closed for about three weeks, built out a full sushi bar, and reopened June 30. Tea Mate moved downstairs. The upstairs now has 20 seats across the dining room and patio, plus eight at the bar.
There are two ways to eat here, and they work differently:
- Hand rolls, walk-in only. Pham rolls his temaki into cylinders instead of cones, which is where the name comes from. Fillings range from bluefin and yellowtail to eel with foie gras. You can order rolls one at a time or in chef's sets of three, five or seven.
- Omakase, reservation only. At the time of Boulder Reporting Lab's September story, seatings ran Tuesday through Sunday at 4:30, 6 and 7:30 p.m. The 12-course meal was $120 and the 20-course was $165. A smaller version comes with two pieces of sashimi, three pieces of nigiri and one temaki.
Look at the plates while you're there. Pham does woodworking and makes some of the serving pieces himself.
The Kitchen changes owners, and the plan is to keep it the same
The pattern continued into October. Dayton told 5280 that Half-Eaten Cookie is acquiring The Kitchen American Bistro in Boulder and Denver from founders Kimbal Musk and Hugo Matheson. The Boulder restaurant opened on the Pearl Street Mall in 2004.
This time there's no rebuild. Dayton told the Daily Camera the approach is "business as usual," with no major changes planned for the spaces, staff or menus, though there might be "some tweaks." He told 5280 that eventually he'd like to bring in beef from Corrida Cattle Company, the ranch-supply business he started with McCandless. For now, your usual order at The Kitchen should still be on the menu.
A short plan for fall evenings
- Early-evening drinks in North Boulder: Cinq à Sept, 4 to 5 p.m. daily, for bread, cheese, oysters and jambon de Bayonne.
- Mid-afternoon downtown: San San's progressive happy hour, starting at 3 p.m.
- A Friday splurge: San San's prime rib, while it lasts, or a booked omakase seat at Temaki Joint.
- A weeknight with a group in South Boulder: Morso, with pizza and the parms.
- A quick, unplanned bite: Temaki Joint's walk-in hand rolls.
