Need recommendation on Chicago restaurant for birthday?

Fogo De Chao.

If you have never been to a Brazillian Steakhouse then you are in for a treat. The Matadors bring around 14 or so different cuts of meat and lamb and pork, etc to your table and it is delicious! It's very pricey though but well worth it and lots of fun because of how unique and interactive it is.

One of my faves is Opera at 13th & Wabash. Sort of an Asian-french-fusion menu. Tasty and interesting. :)

Down the street around 15th & Wabash is M-Lounge, great low-key jazz place to get drinks. They are available for renting out on Sundays. (Also on Sunday Opera has a great prix-fixe menu deal!)

The Cheesecake Factory

or

Grand Lux Cafe

I say either Le Colonial or Topolobompo/Frontera Grill.

Excellent food at Gene and Georgetties- pretty pricey but soooo worth it. I seriously recomend this place- you will need reservations. Only i am not that sure if that is how you spell the name
