What shops are at union station Chicago?

There aren't really "shops" per se, at least in the sense that you'd want to go shopping there, but here's what's available:

On the Mezzanine level:

McDonalds

Jamba Juice

Nuts on Clark

Corner Bakery

Nino's Sanwichs

Pizza Hut

Cajun (which is actually a Chinese-style place)

Burrito Beach

Gold Coast Dogs

Robinson's (ribs and bbq)

65 ("Chinese")

Cinnibon

a bar (I think called the Snuggery)

1 Relay news stand on the NE mezzanine area

1 Relay news stand on the SE mezzanine area

1 currently vacant storefront

Other areas:

a diner/buffet/cafeteria type place immediately east of the grand waiting hall

1 Relay news stand adjacent to the west (original) waiting hall

1 Relay news stand on the east side of at track level, north of the ticket counters

Sometimes a flower stand by the north tracks

a shoe-shine shop and I think a dry cleaners near the Metra commuter rail ticket counters
