Addis Ababa is delicious, but bring a few friends because it's communal cuisine. Penny's Noodle Shop sustained me well through many episodes of extreme poverty, but it's not what I'd call a daddy's-payin'-type place. There was an Italian place on Clark a block or two north of Belmont that the well-paid improvisers (especially couples) seemed to love, but I don't remember the name, don't know if it's still there, and can't vouch for it personally.
