Need info on Chicago are card rooms please

[coolhandkuhn]

Hi all.
I'll be visiting a friend in Chicago this weekend. He's got a conference he needs to attend on Saturday, so I'll have all day free and thought I might check out one of the poker rooms in the area. He lives up in Lincoln Park, and I'm flying in so I'll be without a car.

1) Where are the poker rooms/casinos in the Chicago area?
2) How close (miles and or drive time) are they to Lincoln Park?
3) Is taking a cab to the casino a feasible plan? How about the El?

Thanks in advance.
