O'Leary's is a South Side staple serving up honest-to-goodness food at a low cost without any fanfare. The staff do it all, wait tables, cook, ring up checks. It's kind of chaotic, but the breakfast is hot and filling. One quibble, I ordered the Deluxe French Toast that comes encrusted with cornflakes and was so looking forward to it. I got the regular French Toast... Which was good, but not as good as I imagine the Deluxe version was. My husband got the hot sausage omelet much to his liking. We will definitely be coming back here for a quick, hot, and cheap breakfast next time we are up early enough on a Saturday b/f it gets packed. Best to go 1st thing in the morning. Any later than 10 and you may have wait awhile. Plus, which by 10, do yourself a favor and go to brunch!
