1. Lockwood is super-smart for promoting this 20% discount off lunch or dinner when you show them your Art Institute ticket stub, in honor of the Modern Wing opening. If you want formal environs to help recover from your post-art coma, theirs is indeed a lovely and very convenient option. Terzo Piano on the other hand is arty casual.
2. Open two weeks now, Terzo's service staff is definitely still getting its legs. Lunch there has been averaging about 90 minutes - a long time for most of us to escape our typical weekday maelstrom. I'm checking it out for dinner next Thursday to see how the experience varies from mid-day.
