Monical's Pizza. Nothing close to it.

It must be a regional thing. Like the love of White Castle for people from the big northern cities like Chicago and Detroit or grits for southerners. No one I know that grew up in the Chicago area and went to college at Eastern Illinois, Bradley, Illinois Wesleyan, ISU, U of I, etc. rave about or miss Monical's Pizza. Guess you had to 'grow up on it' to enjoy it. It may be the best pizza in central & southern Illinois but that's not saying much as that area isn't considered a 'pizza lover's paradise'. Kind of like being the 'best Mexican joint' in Winnipeg Canada.
The last time I tried it was 15 months ago at a company-owned store (some of their locations are franchised) in Manteno. The very-thin crust pizza is bland and unimpressive IMO. This may explain why many of the locals like to dress their Monical's pizza with a liberal dosing of the Monical's red salad dressing that is conveniently parked on each table top. The salad dressing is really tasty - but I don't care for salad dressing on my pizza, thank you.
There's also a good reason that they've expanded to 51 locations in Illinois and
ALL of them are located south of I-80. Their pizza would be considered mediocre in Chicagoland. They are not in the same league as Chicago area pizza places with multiple locations like Lou Malnati's, Connie's, Aurelio's or Edwardo's. Let alone compared to the great pizza you will find in gems like Vito & Nick's on the southside or Burt's Place in Morton Grove.
