I just had my one and only experience at Grindburger! We walked into the restaurant and the floors were so slippery! We thought that our feet were wet because it had been raining, so we wiped our feet on the rug by the front door but the floor was still slippery! As the waitress showed us our table, we were slipping and sliding behind her. We sat at the table; even the table was sliding around. I touched the table, IT WAS GREASY! We got up and slide right out of there! If the floor and tables aren't clean, I can only imagine what their kitchen looks like!
