As the ultimate redneck hybrid (born in Texas, educated in Kentucky) I feel like my opinion on this is worth at least $.02...do what you like with it. I have always liked Chuy's and thought it would do great here due to the lack of great Tex-Mex choices. I even went so far as to inquire about franchise opportunities (not seriously, but more out of curiosity) several years ago. At the time they wanted to "keep it in the family" and had no plans to franchise, and even if they did, I know just enough about the restaurant business to never put my money where my mouth is.

Of course, judging by the fact that I have been asked to wait 90 minutes on a Tuesday night at 8:30, that may have been a mistake! Sweet Maria, that places is selling some food!
As Robin noted, Chuy's passed as decent Tex-Mex in Texas (even among the Foodie crowd) and was always a good local place for an inexpensive group gathering, a beer and burrito after a softball game, family night, or a decent Margarita after work. Of, course, you didn't have to wait two hours for a table and they took reservations which makes a big difference. Yes, there were better places, but for "bang for the buck", fun atmosphere, and universal appeal (everyone could agree on it - much like pizza/italian here) it was a winner and I have missed it since movng here!
I find the Tex-Mex here bland and tasting like everything came out of a can. Even the tortillias taste packaged (and probably are as I've never seen anyone making them), and the chips are thick and tasteless - a HUGE deal for me. I was lucky enough to attend Chuy's soft opening and talk to one of the owners, who explained that all the sauces and tortillias were allmade on-site from fresh ingredients using original family recipes. I don't know any other Tex-Mex joints in town that do this (a few of the "authentic" Mexican places do, but it's just not the style I'm looking for)...certainly not the small chains here in town. Field greens in my tacos (along with notoriously surly service - you know who I'm talking about

) or rubbery (!?), wet, sticky tortillias just don't do it for me. I will conceed that the "authintic bagel" factor (see "authintic" bagel threads) may be coming into play a little here...we all have our thing...
For those of you that have had bland food or food "50x better" (really?) Tex-Mex food somewhere else in town I would encourage you to try the house specialties if you haven't already. I think it is a little unfair to judge Chuy's or any Tex-Mex place solely on the quality of their tacos, quesadillas, etc (not that anyone here did...). In fairness, these items are extremely simple (lettuce, tomato, cheese meat) and don't vary too much from place to place. Although, again, the fresh taco shells and pico do make a difference to me. If tacos are what you like, I agree with Robin, head to the authintic places on the Southside they seem to do it best, especially when in comes to those delictable pork tacos.
This isn't Volare folks don't over think it. Tex-Mex, IMO, is all about gooey, savory, belt-busting, all melting together, spicy, goodness. Order the items that best fit this discription. In an apparent effort to please everyone, Chuy's will allow you to ruin your meal by adding the wrong sauce to the wrong dish. Yellow cheese on a burrito? Blech! Nothing against yellow cheese or burritos, but it's only meant to be at Tumbleweed. Stick to the items where they choose the sauce for you (unlees they have a burrito with yellow cheese

)...that's at least a hint that you're ordering something "authentic". And yes, the quotes are there to impart a certain degree of sarcasm, but you know what I mean...
My favorite, the steak burrito, is the spiciest dish I remember ordering in town (without specifically asking for extra kick). It's not Thai spicy "5", but your nose is going to be running half way through. Tender steak rolled in a massive fresh flower tortillia with copious amounts of melted jack (?) cheese and smothered with that amazingly spicy Hatch green chili sauce and served with charo beans and green chili rice....holy crap... I highly recommend it, but it's not for the faint of heart. I have noticed that the heat varies seasonally as the chili's (which I believe I was told are imported from New Mexico) used to make the sauce are a little hotter in the Summer months. There are a few other favorites....the Chica Chica Boom-Boom (is that right?) comes to mind.
Another hint....like most of you, I'm not about to wait 2 hours to eat anywhere so the only time I found we can get seated in less that 20 minutes is at odd times of the day...say a late lunch at 3:00 after shopping or whatever. I have also had some luck right after work on weekdays (5:30ish, but not too long after that the place blows up). Anyone else have any other hints? Good luck and enjoy!
