I recently visited Koi Las Vegas for a Planet Hollywood tweet up for the Expendables movie. We were first greeted very nicely by the Planet Hollywood rep. After we sat down our waitress was very rude and impatient that we didn't know what we wanted to drink. We were told by the PH rep that if we got a drink we would get a ticket to the movie. After we got our drinks our waitress took our money returned with the change, and no mention of the movie tickets. It wasn't until after we tipped her that her attitude changed and she offered the movie tickets. We then left and I left my cell phone there. I called Koi and they informed me that someone had turned it in, but that they didn't hold lost and found and that hotel security would have it. I went to Hotel security who didn't have it, i return to Koi and the manager of Koi tells me that it was up to the guest who tried to turn in my phone responsibility to turn it into security and not the restaurants. After many years of going to Koi in Los Angeles, I will never return to any of their locations based on this experience.
