I second all the above recommendations too, especially the Jack Daniels tour. I haven't spent much time near White House so I don't know too many places there. Here's my .02
If you like beer then check out Yazoo
brewery. Tours are a few bucks I think. You get to try their beers on the tour and keep the pint glass. They have a tap room where you can hang out before/after the tour. Just come early because the tours fill up and the tap room gets crowded. It's on Division street too. There's also the Flying Saucer
behind the Union Station hotel on Broadway. They've got almost any kind of beer you could want.
If you like bluegrass music the Station Inn
on 12th Ave is a hotspot.
There's plenty of good places to eat around town. One of my favorite places downtown is Chappy's on Church
($$$) which is cajun and awesome, just a little pricey. Another is in on Lebanon Rd near Opry Mills call ed McNamara's Irish Pub
. They have live Irish music almost every night of the week, but if you plan on going on a Friday or Saturday night call and make a reservation for the music room. If you like Irish music and are downtown there's another good place called Dan McGuiness
which is on Demonbreum St. They have live music too but I haven't been there in a few years. If you feel like venturing into East Nashville (not always the best side of town), then Prince's Hot Chicken
is supposed to be awesome if you like spicy stuff. If you like NYC style pizza then I'd go to Joey's House of Pizza
(check hours before going) or Manny's House of Pizza
downtown in the Arcade. Joey and Manny are brothers but if you go don't mention them to each other. Apparently it wasn't a good separation.
