I work close to KFEC, I noticed Lego Fest on the sign but was afraid to tell my daughter, it was also on the morning news. That is a good area for some good Tacos.

Hahaha, it was a busy day to say the least! Very fun though. I know the folks that were manning the exhibits HAD to be completely exhausted after it was over..haha. 
I love a great taco, where is the place you’re talking about? Need to add it to my list.
