I agree with both those recommendations, David Burke's and Bin 36. Another good Chicago steakhouse is Gene and Georgetti's if you're looking for the old school Chicago vibe. There are some deep dish pizza options near downtown like Lou Malnati's and Giordano's. There are two upscale Mexican restaurants (Rick Bayless) near there, Frontera Grill and Topolobampo. I'll put in a word for Cafe Iberico for tapas as well. Depending on what type of atmosphere, price range, and food you're looking for, there are tons of options in River North.
