There are quite a number of very good steakhouses that would fit your criteria - Ruth's Chris, Morton's, Gibson's, Kinzie Chophouse or Lawry's (<--prime rib, not steak). Vong's Thai Kitchen has good food but a much more younger/hip atmosphere. Joe's Stone Crab is good, Blue Water Grill as well. I'm a big fan of Cafe Absinthe in Bucktown.
