The pasta for the price at Maggiano's just can't be beat! I went with my Mom and her sister and my bf (Chris L.) last week while in Vegas. I shared the gnocchi and meat lasagna with Chris L. and my Mom and aunt shared the corn pasta with shrimp. The corn pasta was a must for them because they are both on a gluten-free diet so regular wheat pasta just doesn't cut it. I love that a serious Italian restaurant cares about the wheat-free side of life and offers wheat-free options. I also love that a serious Italian restaurant can taste this good and not break the bank.
The wine list is great and the desserts were pretty good--I got the profiterole with ice cream and chocolate sauce and the dessert would've been divine if it weren't for the profiterole.... The two baby boomers at the table each got the (GF) creme brulee and loved it.
So, for what Maggiano's is, I'm giving it 5 stars. It certainly beats the other "cheap" food of Vegas and the price is so much better than the expensive restaurants there. That's a win-win in my book.
