GREAAAAT service!! i've been to this MAC store in the Forum shops many times, and i'd have to say that I am usually pleased. on occassion it can get quite crowded---but you have to take into consideration that its in the busy forum shops, right next to the talking statue of Caesar.
i just visted vegas this past weekend, and stopped by this store to pick up some eyeshadows. i was immediately greeted, and informed of mac's new limited edition line. she showed me different ways to apply the combination of colors, and was not at all pushy about buying other products.
