Every time that I've been to Terroni (at least 5 times) it has never disappointed me. I know that I can recommend it to my friends and they will have a enjoyable experience. The food is great, the ambiance is equally as fun.
I think the major problem with this place is that some of the staff seem to have a bit of an attitude problem. It's really hit and miss. Sometimes you'll have somebody who is attentive and shows a general interest in your meal. Other times you'll just get somebody who seems to have contempt for you. Either way it's a bit of a blemish on an otherwise great restaurant. I don`t know what it is like at the other Terroni`s so I can`t say if it is a chain wide problem or something specific to the Adelaide location.
