Yum. They were at ComiCon this year and they sure were popular. I ordered an original pretzel with cheese sauce and a cinnamon sugar, both in the shape of a mustache of course. Both absolutely delicious too! Each offered something different, sweet and savory flavors. They have other dipping sauces (costs extra) but worth it since the pretzels are freshly baked and fun to eat.
My total was around $10 but the novelty of eating a mustache pretzel is unrivaled. These folks got a good thing going here! Check their website for the schedule of their stops.
