From what i can tell, it's been about 2 years since a discussion on St. Louis style pizza has happened on this forum.
I grew up in the St. Louis area and while living there I hardly ever ate pizzas from the biggest chain of this style Imo's.
I now live in Texas and have been down here for 5 years. For some inexplicable reason i find myself craving an Imo's pizza. They are overpriced and really not filling at all.
If i remember correctly 1 person could finish off a medium by themselves with no problem.
It's the cheese i'm craving. I did eat at one particular Imo's every 2 weeks or so while i lived there, but i didn't order pizza, I ordered a hot roast beef with cheese. This was a really good example of a perfect way to use provel cheese. Toasted french type bread, juicy beef, provel cheese ran through the pizza oven and served with au jus on the side. Best sandwich i've ever had.
I'm planning a trip home soon and i wonder what i will think about st. Louis style pizza after eating some very good new york style pizzas down here for 5 years. I'll let you know if it's changed at all.
One final note, although i didn't eat pizza at imo's, i did frequent a place called racanelli's a fine example of New York style pizza in St. Louie.
