Well, low expectations is probably a pretty good start.
IMHO, Carabba's is a bit better than Olive Garden, at least the one in FL near my parents was. Stick with pasta. The eggplant parmesan isn't really half bad.
The salads are abysmal little iceberg monsters, and I would steer clear of seafood, at least in this area. In FL the dishes made w/ shrimp were pretty good, but I suspect that may have been a fluke. Grilled chicken things are reliable.
Good luck-- I at least hope your office is paying for it! LOL!
