We learned the only thing you can be sure about is that nothing is for sure, during the third round of Caliente’s Breakfast Madness.

Several of the high-profile restaurants remaining in the competition were rocked with losses after last week’s voting.

In true David and Goliath fashion, Viv’s Café on East Tanque Verde Road — a strip-mall eatery with a minimal Facebook presence — took out the Cup Café at Hotel Congress, downtown. The Cup had gone as far as creating its own hashtag, #CupvsViv on Twitter, to generate interest and was one of the most popular restaurants in the game up to that point.

The Happy Rooster on South Sarnoff Drive also pulled off a surprise victory, with a one-two knockout against Mother Hubbard’s on West Grant Road.

It seemed like Cindy Lou’s Café, with its two locations, didn’t stand a chance against The Good Egg, a chain with several spots around town and in Phoenix.

“I was a little concerned about that,” said Cynthia Bosland, Cindy Lou’s namesake.

Bosland had nothing to worry about. The breakfast-and-lunch joint rose to the occasion, beating The Good Egg by more than 100 votes.

Cindy Lou’s has been feeding locals on East Benson Highway for more than a decade. The second location in Three Points has been open eight years.

Bosland launched the restaurant with her husband, Chuck Bosland after a lifetime working in the food service industry.

Cynthia said the restaurant serves all of your typical breakfast dishes, including a plate called The Elvis, which comes with two eggs, any style, two strips of bacon, two sausage links, hash browns, a short stack of pancakes, and your choice of toast or homemade biscuits and gravy.

“Elvis had a good appetite,” Bosland said.

The only matchup that didn’t end in a total upset was Omar’s Hi-Way Chef’s win over Chaco’s Café, a family diner with locations; one on South Craycroft Road and the other downtown.

Viv’s will face off against Cindy Lou’s in the final four. Omar’s will take on the Happy Rooster.

Voting begins today.
