Bartolotta question - Pasta for Entree ok?

I am trying to settle on a nice dinner for upcoming Vegas weekend. I adore Italian food and especially pasta. I like seafood, but not necessarily by itself on a plate. To explain it better, if I'm going to spend $50+ on one plate of protein, it's going to be steak. I prefer seafood as an appetizer or as an element in a dish. So what appeals to me most at Bartolotta are the seafood pastas. I would like to pair one with a salad and a dessert (and possibly soup or another app?). But I have a feeling this is not done at Bartolotta, that I would be almost required to order a plate of seafood to eat after my pasta. And perhaps the pasta dishes are very small and thus simply cannot be satisfying as a main course. (Such at Giorgi Baldi in LA if you've been). Also, I don't want to get attitude from the servers because they believe I am being cheap. Advice appreciated.

As for replacement pasta restaurnts, I've been to Scarpetta in LA so that is out, not sure about B&B as it doesn't fare too well here on the boards. Not interested in Nove, am I missing a good alternative?
