A popular Mexican bakery chain plans to open its first gourmet cake and pie shop in Tucson. Suspiros Pastelerías, based in Hermosillo, Sonora, has 263 shops in 22 states throughout Mexico, and Tucson will be its first market in the United States. By early next year, the company will open two shops in Tucson (5327/5329 S. 12th Ave. and Ajo Way and 12th Avenue) and one in Nogales, Arizona. The U.S. stores will be known as Suspiros Cakes. The company says it has more than 40 varieties of cakes and pies, and they will be introduced in phases each month. “It is very important for us, because it means Sonora is looking to Tucson as an opportunity for U.S. entry,” said Juan Francisco Padres, the city’s economic development specialist for international trade. “We are one region, and part of their market already, so brands like Suspiros see Tucson as a gateway.”
