Original English Text: I went to AAA for their travel service. They could not help me at all with my trip to Belize. They have zilch information and resources. This is a prime destination of American tourists. I was disappointed.

Original English Text: My wife and I have been to this location multiple times, and have only had 1 bad experience where the people in the check out area were a little brain dead that day. (they told us that the rug we purchased wasn't in stock, then it was, then wasn't, then was again...) Other than that, we are always helped right away, and checking out goes quickly. They also have free self serve Starbucks coffee which I always help myself to.

Original English Text: I love shopping at buffalo exchange but when it comes to selling I prefer selling to the phoenix location because the employees are a lot more genuine, there's less of a hipster pretentious vibe there, and I usually sell more there too. Not to mention the tempe location usually turns the music off at 8:30, which gives an unwanted feeling to their guests. I am giving two stars for the sake of finding things at all locations. Go phoenix location!

Original English Text: There's so many choices of food in Las Vegas. Don't choose this place. It is no exaggeration that mcdonalds and arby's have better hash browns, eggs, and bacon. Missed items in the dishes we ordered. All around disappointment to the Las Vegas allure.

Original English Text: Not only is this place in my neighborhood, it is exactly what I'm looking for. I have pale skin, green eyes, and freckles yet I have been cheated out of having naturally red hair by mother nature!! Therefore I have been a fake redhead for at least a decade. You can imagine the cost and damage to my hair I have endured. Fringe has a new dye that is ammonia free! It's basically just a oil and water dying process! I've gone twice in a row and my hair has never been in such good condition. I'm paying the same amount for hair dying as my old salon except here I get a better cut and style and it's not frying my hair! Also Chanel (who dyes my hair) is a totally cool chic and always has interesting things to talk about! This is my new go to salon!
