If you have been looking for a true hole in the wall Mexican restaurant for cheap tasty authentic Mexican cuisine, this is your place. I must have driven by Juan's a thousand times on my way to work without ever noticing it. It is a totally non-descript cinder block building with no windows or obvious entrances. It's a little scary looking, especially since it is right next to the 51. Trust me. You need to check it out. Inside is a bustling family run restaurant that feels like home. The food is really good. I have already been back several times since being introduced to Juan's by a friend. It is destined to become a part of my restaurant rotation.
