I agree with dasmarian. I work downtown, and live somewhat near the Hamilton Place Mall. Downtown sees more tourist traffic, and is definitely busier during the summer months when the fountains are flowing and the tourists' kids are out of school. There are free outdoor concerts in Miller Plaza every Friday night which brings crowds of people, and the trendier restaurants in the riverfront area are almost always full in the evenings. The weather here in August is MUCH more pleasant than it is in FL. But tourists do visit year-round, and spring and fall are beautiful with flowers blooming or leaves changing.
Dasmarian's list is good. For web sites go to
Hennen's,
Alleia, and
St. John's. For other independent restaurants, check out
Niko's Southside Grill or
212 Market. Good restaurants attached to upscale hotels include
Broad St. Grille (attached to The Chattanoogan, one of the best downtown hotels) and
Porter's Steakhouse (attached to the historic Sheraton Read House). Both hotels are adjacent to the downtown convention center and the restaurants see lots of local downtown traffic, but they are obviously subject to the whims of the tourism industry. If you're interested in regional chains check out
Big River Grill and Brewery,
Sticky Fingers (both also have locations at Hamilton Place Mall) and
Blue Water Grille. There are many more good restaurants downtown, but these are the ones I'm familiar with.
For more regular year-round traffic check out the Hamilton Place Mall area. It's the largest mall development in the region. Not just the mall, the surrounding area is stuffed with almost every store imaginable; from Walmart to upscale boutiques. Traffic is horrendous during the month of December, but that's a good thing if you work there. Good places to check out include
The Acropolis (independent Greek place),
The Chop House (excellent steaks), Bonefish Grill, Carrabas, Sticky Fingers, and Big River. Again, way too many restaurants to name them all. Good luck!
Edit: Keep in mind that this list is in answer to gulfgirl's request for good places to work, and I tried to keep within her parameters. This isn't necessarily the list of places where I would take out-of-town visitors for a taste of the local flavor.
