My mom used to make liver and onions fairly often, and I actually liked it pretty well. Haven't had any since before she passed away nearly 28 years ago.
I don't see liver on the menu at most restaurants, but I just was looking at Piccadilly Cafeteria's website (Morrison's in Mobile, AL), and saw they have liver and onions. I doubt I'll get it, as I usually have shrimp or chopped steak there.
