It was all fabulous - I HIGHLY recommend Spoodles!!
It was actually a double add on, but we didn't know that and didn't order it that way. My shrimp was 14 total and I was blown away. We were told right from the beginning that we could add anything on and it was included. He told us that if we ordered the fettucine alfredo and wanted shrimp, scallops AND chicken, we could have it. No OOP cost. Same with add on's to the steak.
DS woke up right before dessert and wasn't happy so he and I waited outside while DH "paid". He saw that my steak said something like $47 and his was itemized with the cost of steak ($27.99) and then scallops $6.99 and scallops $6.99. He asked our server and was told that they doubled our add on.

He explained how the 18% tipping works and told DH that pretty much everyone doubles the add ons if you want.
When we went back the second time, we ordered the steak and each ordered one add on of shrimp. Our server (different this time) asked if we wanted scallops too, but we declined.
Spoodles is, hands down, the best
DDP value. And it is delicious!!!
