Over-hyped and overpriced.  Located in the forum shops in Caesars, Trevi is located right in the middle of the mall.  My boyfriend and I did not have to wait, luckily, but were sat right next to the greek gods water fountain which turned out to be very loud/distracting.  Service was slow because it was a busy.  The food (Italian themed) was nothing special.  I ordered the linguine ai frutti di mare, one of their specialties, which was delicious but expensive for the small portion and lacked enough seafood.  My boyfriend's sausage pizza had onions that were way overcooked.  Overall, I will not be returning and am surprised at the poor value of their food for the great location.
