My friends and I visited Las Vegas for the first time the week of 6/30 through 7/7. We decided that Saturday night we would enjoy a fine dining experience and then see what the nightlife had to offer. We got dressed and headed out to the strip sometime around 7PM. After debating on where to eat we settled on Giada (she is my partner and I's favorite chef after all!). We were all dressed in appropriate attire, however at the reception desk we were treated as though we had walked in wearing flip-flops and tattered shorts. We made our way up the escalator and I approached the desk. A young dirty-blonde haired woman greeted me and I stated that I had a party of 6 and we wished to have dinner. She started to say "Oh I"m sorry but we..." At that moment another blonde haired woman (slightly older) literally nudged her with her elbow and said "be nice". She then preceded to ask me if I would perhaps like to see the menu before we were seated. Essentially she was insinuating that we obviously could not afford a meal there and looked the part to boot. I was infuriated, however being the opposite of what hey assumed I was I played along and agreed to see the menu. We were then whisked away on a tour of the kitchen area and finally seated. The drink menu was very unique (based on Giada's father's favorite films), I had a Hannibal which was great and my partner had the Barbarella (his favorite film) which was equally refreshing. We ordered Giada's favorites and calamari for the table as the antipasto, spaghetti and tortellini for the pasta and shared the porterhouse steak with a side of polenta. The food was amazing just as we expected, however the treatment by the staff left a sour taste in our mouths. There were other patrons sitting near us wearing shorts and t-shirts whom I am sure were not treated as we were. The main reason in my opinion is because we mostly looked Hispanic unlike the fairer skinned individuals who were poorly dressed. While the food was amazing, we will not be visiting Giada again. I myself have experienced true Italian hospitality, unfortunately it was nowhere to be found at Giada.
