Soda Tsunami and Fiesta Cancun Mexican Grill merged, and owners say customers love it

IDAHO FALLS – Customers at Soda Tsunami in Idaho Falls may have noticed a few changes.

Soda Tsunami recently partnered with Fiesta Cancun Mexican Restaurant to offer an expanded menu for customers.

“We’ve always had little pizzas and cookies and bagels — that kind of stuff. But people have asked us for a long time for food,” Soda Tsunami co-owner Amanda Rosenberg tells “Jonathan (Rosenberg’s husband) and Ricco Lanuaze (Fiesta Cancun owner) have been friends for a long time. They started talking, and we decided it would be a good merge.”

Jonathan says the merger allows them to use some of the extra space in their restaurant better. Soda Tsunami began offering Fiesta Cancun menu items about a month ago, and they agree the partnership has been mutually beneficial.

“I brought my menu here to join them in this venture,” Lanauze says. “I was having a hard time trying to find the right items because we aren’t able to have a whole kitchen set up, so I needed to offer something that would be easy to cook over there, bring over here, and still can be fresh.”

Lanauze opened Fiesta Cancun at 115 South Higbee in September 2018. He will continue to operate his restaurant on that end of town, while offering specialty items from that menu for Soda Tsunami’s on-the-go crowd.

“The chili verde here — that’s what 90% of the people get. It’s so good,” Amanda says.

Chili verde is a combination of pork tips and green salsa. It is served with rice and beans or in a burrito.

New menu items will be added next week. It will include burritos, street tacos, quesadillas and fiesta bowls, which is a combination of meat served over rice and topped with blended cheeses, sour cream and pico. Side orders of rice and beans will also be available, along with chips and salsa and tortillas. A kids menu will include a free quesadilla option for kids 6 and under.

“So if people come in with their kids, they don’t have to worry about spending $5 or $6 on something (that the kids probably aren’t going to eat),” says Lanauze.

The Rosenbergs opened Soda Tsunami about three years ago. Its menu includes cookies, specialty sodas and drinks, smoothies, coffee, hot chocolate, steamers and other treats. It also has “spirit drinks” for each high school in Idaho Falls.

Though this venture is just getting started, all the parties say they’re grateful for the support of the community, and they’re excited about the growth.

“It will be awesome to see two small-business owners in Idaho Falls getting together and build something big,” Lanauze says. “The sky’s the limit.”

Lanuaze is opening a second Fiesta Cancun restaurant inside the building formerly occupied by A Little Bit of Mexico at 465 East Anderson in Idaho Falls. It will open in the next four to six weeks.

Soda Tsunami is at 3460 South 25th East. Its hours of operation are 9 a.m. to 9 p.m. Monday through Saturday, 9 a.m. to 10 p.m. Friday and 10 a.m. to 10 p.m. Saturday. The new food menu opens at 11 a.m.

Fall River Electric customers may see a decrease in their power bill in January

ASHTON – As of Oct. 1, Bonneville Power Administration implemented rate increases for both wholesale power and transmission costs to 143 northwest electric utility companies, including Fall River Electric Cooperative. Not only did the board determine the co-op could absorb the most recent BPA increase, but it authorized a decrease in the kilowatt-hour charge. For the average year-round residential member, this rate adjustment will result in a slight reduction in the monthly bill. Monthly costs fluctuate, depending upon the amount of power a member consumes. These rate changes will go into effect on Jan. 1 and will be reflected on member statements in February.
