T&C Tobacco is in West County off of Manchester road about a mile West of highway 270. This is my go to place and I'll explain why.
One reason is that it is very close to my house, only about five minutes. But who cares about that unless you live close to me.
Even if it was far from me I think it would still be my go to store/lounge. The store is decently sized, lounge in the front of the store with a few chairs and a big screen. The walk in humidor is in the back of the store and is one of the largest in the area. They have a great selection of cigars and the prices are good to average.
The staff is extremly nice and knowledgeable. They leave you alone if you just want to browse or if you want help they will show you around the whole humi giving suggestions.
The cigars are always in great condition. The best I have seen in all of St. Louis. There are never any problems with cigars, these are kept perfectly. I normally don't smoke my cigars straight from the store, but these are ready to go.
This place is a must try if you are in St. Louis.
