there aren't many mid-priced restaurants in vegas. it's either celebrity chef 4 $$$$ restaurants, chains, buffets, or you have to drive off the strip for more reasonably priced food. thus i think Olives is a pleasant compromise. some dishes in the $20 range, and good flavors. notably, the bread basket was delicious -- currant, cheese crisp, etc. yum
the butternut squash tortelli was quite sweet, thus hard to make it as a single entree. the shrimp scampi risotto side was decadent and buttery. brick oven roasted free range chicken decent. entrees large, and if you're lucky, you'll be seated by the window for a view of the fountain show.
