This place feels like an upscale soda fountain/ice cream shoppe with a Cheesecake Factory-like menu. Service was a bit slow initially. It took awhile for someone to come over and take our drink orders but it was fine because the menu is pages and pages long so it took awhile for me to decide what I wanted. Service was good after that initial lag. (Btw, came here on a Friday night after 1 a.m. and it was about 75% full when we arrived and most tables were taken soon after we got there.)
I ended up ordering the Pasta Carbonara and absolutely loved it! To drink I had a cocktail called Grape Crush. Though a bit watered down it was very sweet and tasted just like candy so I enjoyed it. I tried my dining companion's fluffer nutter milkshake and it was so sweet, rich, thick, and creamy with a strong fluffer nutter taste to it - in other words, delicious!! Had a table inside right by the patio so it was a great spot for taking in the view of the Strip and people-watching. Overall I was really satisfied with my experience here and would definitely come back again!
Edit: I went back in September and once again I got the Pasta Carbonara and my dining companion got the Tomato Basil Pizza (so good but also so huge!). We split the Classic Sundae with caramel sauce for dessert. The sundae was just ok, I've definitely had better and it could have had more caramel.
