I found an AWESOME sandwich place in a random neighborhood (maybe South Park, maybe Burien, maybe ???) The joint is called Cemitas Poblanas. They are located at 805 South 112th Street in Seattle. It is in the same parking lot as a Chevron gas station and a teriyaki place.
They serve amazing sandwiches from Puebla, Mexico. Fresh, yeasty rolls with huge slices of avocado, cojita cheese, grilled chicken, and a bunch of other goodies. One sandwich could easily be lunch for 2.
I also saw a lot of people eating their shrimp cocktail and tacos. Will have to give them a shot next time!
