Not quite what we were expecting. This wasn't so much a breakfast taco tour, as a three stop "choose your taco" tour in the comfort of a nice van with a very friendly tour guide driver.
Prior to this tour, we can just had the Migas taco at Veracruz All Natural and thought that the breakfast taco scene in Austin truly was as big of a deal as the buzz led us to to believe. During this tour, we started at El Chilito and were told that they were one of the only places outside of San Antonio that had the "puffy taco" style, so we tried that with picadillo beef and another Migas taco. The puffy taco was unimpressive, and the "puffy" tortilla just felt thicker and tougher than usual. The Migas taco from here was also super boring. The free queso that our group shared was pretty tasty, though.
Next we went to Papalote where we tried the carnitas and Alambres tacos, both of which were actually very tasty, but neither of which was a breakfast taco (because we got to choose whatever we wanted, and our guide didn't really recommend the breakfast tacos here). We also got the horchata and hibiscus agua frescas with the meal, which were nice.
Lastly, we ordered in advance for The Taco Joint because it gets so crazy busy, so finding seating for all of us was a little tricky, but we found a big table for the group and ordered another Migas taco, as well as the potato, egg, and cheese taco. Again, neither was particularly impressive, so kind of a bummer. Fwiw, I would encourage this tour add Veracruz All Natural Migas taco to the list and make it more prescriptive after identifying the best three or four breakfast tacos that can be hit in Austin in a morning.
We had fun, so no regrets, but it wasn't what we expected, and now we feel that the breakfast taco scene is overhyped. :shrug:
