Trevi would not be a destination restaurant in Vegas nor would it be my first choice for a business dinner, which is the occasion that we were there. Trevi is situated in the the Forum Shops with majority of its seating in the mall. The inside of the restaurant is very nice and comfortable with its high ceilings, open kitchen and dark colors. Sitting in the restaurant rather than the patio is highly recommended. The dinning room keeps all the mall noise out and it feels more like a restaurant rather than apart of a mall food court. The service was great at first with prompt delivery of menus, drinks, bread and appetizers. After the appetizers were served service became nonexistent. After receiving the bill, it turned out that the gratuity was already added. It was then obvious as to why our server began focusing his efforts on smaller tables...weather he sucked or not he was still getting his tip. The food was not great or bad...it was just something to cure your hunger. We started out with the bread that they serve to each table and it really served no purpose but to fill your stomach with its complete lack of flavor. For appetizer we shared a couple of pizzas that were the best part of the meal. Despite the canned tomatoes on the margarita pizza they were very good. For dinner I ordered the bolognese pasta. The pasta was cooked perfectly but the taste reminded me of Olive Garden. We all shared dessert. The Tiramisu, the hot molten chocolate cake and the ice cream were the highlight of the meal, with the chocolate cake being the best of the three. Overall the food was bland, unexciting...really nothing special. The food is on the same level of Olive Garden, but the price is on the level of finer dinning. If you're thinking of Trevi for dinner, keep walking and go to Spago instead.
