Rosemont is close to O'Hare Airport and has a lot of convention business, hotels and offices. Unfortunately, this means too many restaurants are rather corporate. You might start looking at these threads:
Rosemont is also close to both the Edison Park neighborhood of Chicago and the suburb of Park Ridge.
re: Eldon Kreider
From these links, I can provide two personal recommendations:
Flamingo's Seafood (Mexican) is well worth a visit.
Topa in Elk Grove is a place where we dine frequently. I am always quite happy with their appetizers, salads and fish offerings, whereas my wife is frequently delighted with their steaks. http://www.toparestaurant.com/Welcome...
I have not eaten at Rosewood in Rosemont, but it is operated by the same family involved with Topa.
If your husband is spending 12 hours/day in meetings, does that mean that YOU can head elsewhere for lunch (or even dinner)? Downtown is only about an hour away via the blue line.
I guess my point is that I understand that your husband might not want to venture out after a long day of meetings, but there's no need for you to be stuck out in Rosemont if you don't want to be out there.
Well, we have returned from Rosemont & I thought I should report back. We tried Flamingo's on our first night and had a fantastic meal...my DH is still talking about it. I think he has been dreaming about the salsa. The second night we ate at the hotel (Hyatt Rosemont) and although it was late, we were tired and in a hurry, we had a decent burger that certainly exceeded my expectations. For lunches, we tried Udupi Palace for dosa (delish) and NoMI. Overall, a great trip. Thanks for all the recommendations - we look forward to returning next year.
