For the uninitiated, Don Juanz is on the west side of Airline Drive, between Splash and Strawn's and almost across from Lowe's. I say that because it is hard to spot in the shopping center.
I normally shun places where one has to order at the counter, because I equate that with slow and surly service at fast food restaurants. Definitely not the case here. Service was fast and friendly. As soon as I ordered, I saw someone fixing my margarita and it and chips and salsa were delivered within a nanosecond of my sitting down. My shrimp tacos (I loved the full leaves of cilantro) were delivered in a timely manner. I was asked twice if I needed anything else. I went at lunch and the place was busy but quiet. I wish there were an option to rate the place 4.9. I'm marking it down only because of my aforementioned dislike of ordering at the counter. I definitely will return when I'm next in Bossier City at lunchtime.
