OSF opened at 11:30am. Got there about 11:45am. The train seating area was taken. About a half-dozen patrons were visibly seated at tables in the main dining room area. A couple parties waiting on the side to be seated. A couple parties waiting to check in. Then there was my party of four. I checked in; was told it was a 10 to 15-minute wait. Huh? The large restaurant was empty. Four or five more parties checked in and got seated. So there we were, waiting the 10-15 minutes to be seated, in the lobby, by ourselves, while staff milled about. Finally, a gal asked if we'd been helped. Well, no -- we were watching everyone who checked in after us be taken care of. Absolutely ridiculous, and I was not quiet about my disgust. Should I have asked about our seating? Perhaps yes, but how hard is a list of 10 or so to manage? There was no longer anyone after us waiting. The gal who sat us apologized, as did the manager and our server Summer. I was beyond upset, especially since this restaurant that was celebrated for 30 years of being in business couldn't handle a less-than-half-full capacity. My kids were hungry. We arrived at the center early and waited for OSF to open because they WANTED to eat there. Eventually, we got a free appetizer and our tab was comped (I refused to order anything for myself and wanted to pay the tab but was denied). They cited the new staff as thinking we were accommodated. We also almost got to eat the adjacent table's meal when the waithelp didn't know who he was delivering to. Summer was great and I did apologize because she had to deal with the situation. But the whole situation (as well as the less-than-tasty entrees and spongy-textured chicken) has left a very bad taste in my mouth. Actually hadn't been to OSF in a while. Not going back. Not recommended, but good luck if you go.
