Red Iguana has been around for more than 30 years. They didn't start as a supposedly fancy Mexican restaurant. They did offer some unique, especially for the time, dishes, like their famous moles. Word got around, they had a permanent line out the door and they developed a few dishes that are a little more upscale and intended to appeal to their new clientele. But if you go there and order chicken tacos or cheese enchiladas you are going to get pretty much the same thing you would have gotten in 1985. Which is to say, those dishes are basic. There's nothing fancy about their non-fancy menu choices. They are decent, but nothing special. People who go there and order those items often go away wondering what all the hype was about.
The hype has gotten a little out of hand, but Red Iguana is a good restaurant. Even better if you order the right stuff. Their mole is good. They've been making it since the very beginning. They have incorporated it into several of their menu items and you can buy it on the side. That said, mole is not for everyone. Some people I've talked to were confused about what they were eating. One guy called it a sort of dessert thing. Holy ****, if you eat mole thinking you're having dessert , well yeah, you're gonna be a little disappointed.
My personal recommendations are the Mole Amarillo and the Tacos Don Ramone. My wife get something I can't remember the name of, but its a stuffed park dish smothered in mole. My son likes the chicken enchiladas, but I can tell you, they are basic as basic can be. Nothing wrong with them, but yeah, any other place in that neighborhood (it's the neighborhood I grew up in) will probably have chicken enchiladas just as good or better.
