Renowned restaurant that’s actually worth it

My mom is visiting from NYC for a few weeks and I’d like to take her out to dinner. For the most part we’re doing my favorites(low key, international foods, RHR etc) but would like to take her out to one more upscale restaurant.

She’s VERY into lists and restaurants that are renowned (Michelin, NYT articles) etc — an area of eating I’m not too familiar with in regards to the Chicago scene.

Would love to crowd source any opinions for a more up scale, doesn’t have to be super fancy meal, where there’s a real focus on good food over ambience / drinks.

Omakase is off the table, just because I think my mom will make a snooty comment about sushi in nyc being better
