Leaf and Ale is a pretty nice little store. The selection is slimmer than some, but it's got a nice little smoking area with high back leather chairs; they even host a pipe club meeting there once a month.
Another good shop that I really like is
Smoky's. It's down the road a bit from Leaf and Ale, near West Town Mall, right beside the Starbucks. Smoky's has a much larger selection of pipe tobacco, and a separate smoking lounge.
Also, if you venture up to the mountains (I highly recommend it as I grew up there), visit
The Gatlinburlier in Gatlinburg. You'll be hard pressed to find a greater group of guys. Extensive tobacco selection, and very unique blends. It might seem like a touristy place, but I buy more tobacco from there than anywhere.
