GREAT Italian restaurant. Started in bloomington IL and has now spread throughout the midwest. I am yet to have a pasta dish that I didn't love. Their delicious homemade bread and oil/pepper/parmesan they put out on the tables before your entrees is reason enough to come. I would say its closest competitor/comparison would be Olive Garden, but you get a higher quality meal at a slightly lower price here.
One great option is getting a half-portion (my dates here have always loved this) where you can get a half-portion of your favorite pasta for 8.99. And it is more than enough to fill up most ladies! I highly recommend Biaggi's for a date night or nice family dinner.
The reason I didn't give it 5 stars is the noise. They have never done a great job of sound-proofing their restaurants and during peak hours it can get quite noisy.
