Thanks to those who replied. However, we decided to go up to Hillery's yesterday around 5:30pm after some shopping in Vernon Hills. Sometimes, you have to live dangerously and find things out for yourself.
First, we decided to call ahead as suggested on their website. It took 4 tries over about 15 minutes before they answered. The phone wasn't busy, they just didn't pick up. Then, my wife ordered...and when she reviewed it after placing the entire order it was only then we found out they had no beef ribs or fried okra - both of which we had ordered. So, she had to go through the whole thing again with our changed order. We wound up with tip dinners for us and wing dinners for the kids along with some hushpuppies and onion rings.
Too bad I didn't wait to read gp60004's and Cathy2's responses both of which I totally agree with. The tips were lean but a bit stringy at times with no noticable smoke ring or real smokey taste which surprised me since there was a very large aquarium style smoker in use. We ordered them dry and there did not appear to be any rub on them. The hushpuppies were dense and heavy and the fries were the typical frozen variety. The kids said the wings were "ok.' The sauce was, indeed, heavy with chili powder which I found totally overwhleming.
Overall, a disappointing experience.
