The Illinois Center is the underground shopping mall that connects to the Hyatt Regency labyrinth. There were a number of places to eat, but Kevin and I settled on Houlihan's. It is a classic anything-American restaurant. You can get steak, pasta, jambalaya or fajitas. We, however, were using it mostly for breakfast. Kevin is a big fan of the traditional American fried pile: funny little breakfast sausages, overcooked streaky bacon, mountains of scrambled egg stuffed full of yellow food coloring. You know the stuff. He was very happy, at least until he discovered too late that they had an excellent-looking omelet bar.
As for me, I do like a good corned beef hash. Sadly that wasn't on offer, so I settled for a few sausages and then hit the coffee and carbohydrate. I wasn't expecting to have time for lunch, so I figured I should stock up on stimulants and energy. Good muffins, good pastries, thank goodness I would be on my feet most of the day and able to walk off all that weight.
We did try the restaurant for dinner one night. I had some shrimp pasta, while confirmed carnivore Kevin tucked into a Black and Bleu New York Steak. Both meals were of good quality, but not outstanding. The restaurant is a good place for a quiet evening meal as the layout involves a lot of alcoves with big wooden seats. It is very cozy.
The price range I have quoted is for dinner. You should expect to pay around $10 for breakfast. The restaurant is part of a chain with branches all over the USA.
