Steak 'n Shake review: service and cleanliness

yesterday 10/27/19 was at Steak n Shake at 109 Regency Pk Ofallon Illinois went in 2nd in line to be seated. Only couple of waitresses that were so busy on phone could care less on sitting us. One lady was clearing all the dirty tables. To make a long story short we left because after standing there for 15 min and being ignored! I see why a lot of these place are being [censored] down! Also my husband used restroom while there said it was the most dirty bathroom he has been in for a long time! get it together staff, clean care about your place you work at, care about customers! I would love to be mgr there and totally give the best service and cleanest place to eat at!
