Spruce up that carnitas taco, $2.50, with some lime and pickled red onions. 

Don't let the line intimidate you ... The downtown spot Street Taco and Beer Co. can get pretty packed with businessfolk during the weekday lunch rush. But there's an upside to the assembly line approach: It's freaky fast!

Some of the crispier taco meats like carne asada tend to suffer after spending time in tubs, so I decided to work the system: carnitas! Marinated in spices and then slow-roasted in an oven for four hours, they are a soft and magical meat.

These carnitas can sit as long as they want, because they aren't trying to be crispy. They are moist and fatty with big chunks that you can rip off and shove straight into your mouth. I would eat them with a ladle if I could.

This isn't to say that the other meats here aren't great. (The line moves fast after all, so they probably don't sit for long.) But honestly after this taco, it will be very hard for me to order anything else.   

Insider's tip: This place really does have one of the best salsa bars in town. Don't miss out on that blended avocado salsa laced with bright cilantro ...
