Glad you made it to Austin. And discovered breakfast tacos. The best thing about this town is the tex-mex breakfast. It's the reason I could never live anywhere else. But while breakfast tacos are the default, the breakfast of choice is migas. I've never seen them up north, but they make every other breakfast obsolete. And for the question on breakfast tacos -- the eggs are always scrambled and combined with potatoes, or bacon, or refried beans, or chorizo (variants are rare), virtually always in a flour taco. Then you toss on a little salt and salsa or pico de gallo. I think the potato combination is the worst of the four.
