Olive Garden is plain ol' Olive Garden. It's definitely not on the level of fancier restaurants like Maggiano's or Brio, but it does make you really full especially if you're craving some soup and pasta.
I usually order the Chicken and Shrimp Carbonara with chicken gnocchi soup. The breadsticks usually come out hot and fresh and my friends tend to order alfredo sauce that compliments the bread sticks very well.
Some of OG's more popular items seem to be: zuppa toscana, children alfredo and the tour of Italy (lasagna, chicken parmigiana, and alfredo).
Honestly, I wouldn't mind coming to OG twice a month if it means I get to have the creamy chicken and shrimp carbonara.
Service is hit or miss, but most times it's done well.
