I tried to go at Sunset, had reservations at 6:30pm and we were immediately seated. Finally the sunset at the very end of dinner. Next time I'd go at 7pm. Seeing the strip lit up was nice. Ask for a window booth so you can see the sunset and lights on the strip, or else sit outside on the patio.
One of us had the shrimp pasta fra diavolo. Very hot! I eat jalapenos and such, this was much hotter. Make sure that you can take really hot food. Another had the lasagna. Wow! Very good! I would highly recommend this. I had the Ventano Tortellini. It is cheese tortellini with chicken and mushroom in pink sauce. It is very tasty. The three meals, no drinks, after taxes were $64.
From the menu online, it appears that the lunches are the same thing for about $5 cheaper. Not sure if the serving sizes are the same or not though. And no sunset view would come with that either.
Good food. You need to try it.
