Mas Cafe is a small roadside coffee shop in Wallingford built around Mexican breakfasts and a short list of sandwiches. The bacon breakfast sandwich is the calling card: a fluffy Macrina bun holding a crackly-edged fried egg, grilled onions, a red chile-spiked aioli, white cheddar, and a heavy pile of bacon. A sausage version swaps in two thin patties and nutty provolone for those who want it. The breakfast burritos have their own following and are frequently cited as the dish regulars keep coming back for.
The space is compact and counter-driven, which means lines form during busy stretches, but service moves fast and stays friendly under the pressure. That combination — quick turnaround, low prices, consistent food — has built a steady base of repeat customers rather than a one-time crowd, and Mas Cafe has picked up a reputation as one of the better values for breakfast in Seattle.
