Cornerstone Gym in Chicago?

Does anyone have info on Cornerstone Gym in Chicago. It's located at Harlem and Higgins. They have boxing and Muay Thai there. Is it good place? Do they have a website? Any info appreciated.

Anyone? Hmmmm, that sux. Just you all don't think I'm halloucinating it does exist, i passed it the other day. It's at Harlem Ave and Higgins Ave... right off I-90 Harlem exit. It's been there for about a year I believe. They have boxing and muay thai there, at least that's what advertised on storefront. Just wanted to see what everyone else knew before i went in to check it myself.
