During my recent trip to Vegas over the Christmas holiday, my best friend and I decided to visit the Mandarin Oriental Tea Lounge for a relaxing late afternoon away from the fanny packs and liquor slushies. \n\nI'll start with the good...\nThe hotel itself is very chic as is the Tea Lounge. Beautiful Asian decor with a view of the strip you could find on a postcard in a hotel gift shop. A clean and upscale environment but without a pretentious air that frequent accompanies \""high tea\"".  The hostesses were elegantly dressed and had us seated almost instantly.\n\nIn terms of food, I was impressed with the spread. The scones were delicious especially when accompanied by strawberry rhubarb compote and clotted cream. The selection of tea was lovely. My favorite being the matcha. \n\nNow, the bad...\nThe sandwich selection they offer includes a curried chicken salad, which contains nuts. However, nowhere on the menu did it specify the use of nuts in any of the offerings. The waitress also gave an extremely detailed run down of the types of sandwiches, scone toppings, and desserts yet failed to mention nuts being in any of the food aside from a pistachio cake. For the record, I am deathly allergic to peanuts and cashews to the point that I carry around multiple Epi pens in my purse everywhere I go. \n\nWhen I bit into the sandwich, I started to feel sick and I took a closer look, only to see a small piece of nut that I couldn't identify off the bat. When I flagged down a waitress to ask about what kind of nuts were in the items, she panicked and left to ask the chef. When she returned, she kept firmly insisting that I was fine because it was \""just walnuts\"" but ANYONE who knows ANYTHING about nuts knows that almost all tree nuts are processed in the same facilities. When I tried to ask about nuts being in any of the other desserts, she acted annoyed to be bothered by me again. \n\nI was appalled by how it was handled and I felt ill for the remainder of the day because of that ONE bite of sandwich. I was almost offended to see that they automatically included 18% gratuity to the bill because I would have left $0 if given the opportunity.\n\nI admit it was irresponsible on my part not to ask but the waitress had given such a precise account of ingredients used in other items (ie: eggnog truffles, bubblegum flavored French macarons, black forest ham sandwiches etc.) that I thought I was in the clear. I suppose it was my error to expect such a highly regarded establishment would care about their customer's dietary restrictions. \n\nI REALLY REALLY REALLY don't enjoy writing bad reviews (as you can tell from my profile) but it's necessary in this case to warn other people with severe nut allergies! I'm lucky that all I left with was a bad stomach ache. I really hope in the future the Mandarin Tea Lounge is more consequent of their patrons' needs.
