There is a day of the week devoted to tacos. It is Tuesday, and it is now my special day ...

On said Tuesday, you can walk into a Fourth Avenue bar and receive a plate of gorgeous local veggie tacos dotted with micro cilantro and lime crema. These beauties are an Instagram post waiting to happen: Ermanos Chef David Valencia Jr. takes heirloom carrots from Sleeping Frog Farms and braises them in brown butter for just long enough to create a sear. The carrots and the grilled corn kernels are still partially raw, leaving them snappy and fresh like a little salad. Paired with the fruity pink Prickly Pear Wheat from Borderlands Brewing Co., it was a lovely lunch. 

David rotates through a few different Taco Tuesday specials — including gems like the shrimp a la plancha and pulled pork barbacoa — so check the Facebook page to see what he's doing that week.  

Interesting newsy bit: On my recent visit, I peered into the kitchen and saw the reina of Tucson tacos herself: Chef Maria Mazon of Boca Tacos + Tequila. Apparently she wasn't cooking the tacos that day, but told me she was working on a secret partnership with Ermanos, info coming soon ...
