Im here and am looking for some fine dining places to eat DT  
any suggestions ?

Gibsons and Hugo frog bar are really good.

Go after midnight and request the chocolate shake .... It is awesome!

Sorry, I can't be of much help, lol. I haven't been DT in over 10 years so I'm sure many of the restaurants I used to hit are out of business. But Gino's East has pretty good deep-dish pizza

That is a hard question in Chicago.  It really is quite the food town.
Start with the basics and hit Carmine's for Italian.  It's a Rosebud restaurant but I think the best of the group.
Best newcomer for me in the past year or so has been Beatrix.

Oh, and stick with Lou Malnati's for pizza.

.....the chocolate chip cookies.  Delicious.

Even though I am in the Oak Brook area I know that Gibson's is wonderful! There are so many places you can choose from. It really depends on what you have a taste for... I mean food wise.  
wink wink.

Great bar scene.  Young and hip.  D.J. in lounge area.  Food is awesome.  Great people watching.  Also, I hear that every Monday night is Lady's night were the raffle off a pair of Christian Louboutin's.  That in itself tells you what kinda place it is and who it caters to.

I think they were asking for first hand recommendations.  Have you been to any of those 85 restaurants and can you personally recommend any of them?

Italian: Nico (it's won a bunch of awards, and is relatively new)
Vietnamese: La Colonial
Mexican: Mercadito
Steak: Benny's Chophouse, Bavette's
Modern American: Celeste (a personal favorite), Gilt

I guess you didnt read the link..... many of the resatuarants on that list have been discussed in this forum in the past. This link is from a foodie.... you do know what a foodie is right? its still a nice list to have but then again you are the superior one for posting your opinion of good restaurants

Piccolo Sogno
Volare
Nando Milano Trattoria

Two of my favorites. Frontera for authentic Mexican, Rick Bayless place. Catch 35 for high end seafood.

One of the best Italian meals I have ever had!

The Italian Village Downtown is AWESOME!!! Best Linguine w/Clams! The ambiance is cool too!
