Been here for a concert and a game. Both were great, but if you want good, WARM food eat at one of the restaurants at the shopping center's entrance before you go to the arena.
The Sunday "Farmer's Market" was very disappointing - it was basically a flea market with one guy selling peaches and tomatoes. Check out the market over at the Barrington Arboretum (Higgins & 59.)
Tip: Ask for your 3 hours back. This was a circus act that went on for way too long. Extreme waste of time. They must have legitimately tried to find such talentless karaokesingers.
