We walked here after a visit to the Museum of Science and Industry. I had this visit lumped together with the Robie House and Rockefeller Chapel - both about a block away from Oriental Insitute.
The Oriental Insitute was an interesting museum to see. There were a great amount of artifacts from the middle east. Many of the artifacts were small - like small pots, jewelry, and such. There were some large items that were very impressive, as well.
The museum took between 15-30 minutes for my group to go through. In fact, since the high schoolers I was traveling with were more into "big" things than the "small" ones, we really could have done it in 10-20 minutes...making the $7 suggested donation a little high for our purposes. The boys I traveled with were excited to see the "stuff from Egypt" but then the expectation fell somewhat short once they got there.
The museum has a "suggested" donation of $7. Because I had read that the museum was free (on tripadvisor and several other sites) I was not prepared to dish out the cash. I stated that I would make our donation at the end of the tour, since the entrance and exit were both at the cashier stand. In doing so, I got the feeling like I was the anti-christ or something, and suddenly our purses and drawstring bags were a problem...
As we were trickling out of the museum, we were being "eyed" heavily. Our group was 14 total...there was not really enough staging space for 10 of us to be hanging out waiting for the rest of the group...at least not without feeling like we were doing something bad. If the weather had been 15 degrees warmer, we could have waited outside, which would have put us more at ease.
