This Houlihan's has been a favorite of mine for some time. It's not necessarily that the food is that much better at this particular one than any of the others across the country, it's just that it's in the cool Old Orchard Mall. This means that it's a really nice place to take a walk after you stuff yourself full of good food at Houlihan's.
The food at Houlihan's is just excellent. They have a salmon dish that I love and are willing to work with me and my food issues and make sure no butter is used to prepare the dish. To me, this scores big bonus points on any restaurant.
The pot roast sandwich special is also quite good at this particular Houlihan's.
Not long ago Old Orchard Mall was dying. It was then bought and a major restructuring came about. The place is now up-scale, has movie theaters, restaurants and great stores. So, once you manage to find a place to park (the one major flaw with the place) you can take a walk and find plenty to look at.
Check out the Barnes and Noble. It's enormous.
As for Houlihan's great place to sit down and eat. Decent food and the prices won't break the bank. The atmosphere is right for eating and conversation.
