I purchased this voucher on January 2nd and look to use it January 4th. I was staying at the McCormick Place Hyatt and it was snowing so it was a 30 minute drive to the establishment. Before we arrived I checked the website there isn't anything that says the hours of operations, so I googled it and google said that they were open at 12 pm. I get to the location at 1pm and we were skeptical if they were open but the door wasn't locked so we went in. We waited for about two minutes for someone to come greet us but that never happened, so we just finally yelled out hello. When the man came out he said were not open, so I immediately look at the door and the hours of operations are posted on the door open from 11:30 am Sunday-Thursday. I asked why we're the doors open if they were closed, the guy says he forgot to lock them. So I'm now starting to get aggravated seeing how I just drove from one side of town in cold snowy weather to this restaurant but I calm my nerves and ask to speak to a manager. The guy tells me there isn't a manager working right now but he will call him and when I speak to the manager who name was Jullion he explains to me that there "winter hours" on Sundays are different and they don't open until 2 pm and I should've called to make a reservation because that's what the groupon says. So I'm like we'll I don't have a groupon, I have a voucher through Amazon local, and it doesn't state that reservations are needed. His answer to that was I don't know anything about the Amazon local deal and that it was nothing he could do for me but to call Lydia tomorrow and she could compensate me for my trouble. So sure enough I call today asking to speak with Lydia and Jullion answers the phone. He now has a bit of an attitude telling me that everyone in this neighborhood knows what time the hours of operation are. Ok so now I'm thinking are you trying to tell me that you only serve the people of that neighborhood. So again I explain to him that I'm not from that neighborhood and that it should be posted somewhere and not through word of mouth. Jullion is now asking me what do I want him to do, there is nothing he can do and I said I know that's why I'm asking to speaking with Lydia. So Jullion places me on hold and Lydia gets on the phone saying how can I help you, I explain to Lydia everything that has happened and she starts to attack me. Lydia is on the phone yelling at me, telling me that I should've checked the website, I should've read my groupon, and if it were her and she lived on the south side she would've called before she drove to the north side. So I explain to her that I have Amazon local it doesn't say anything about reservations, their website doesn't list a time of operation and the door even says they were open. Lydia again yelling that I already have 50% off,to go through Amazon to get my money back and that she's not going to be on the phone arguing with me for 20 minutes. I'm outraged at this point because I've never been treated in such a manner, I explain to her that she shouldn't be on the phone speaking to me in the manner that she was seeing how I'm supposed to be the customer and Lydia hung up on me. I immediately gets on the phone Amazon for my refund. I will never ever visit this establishment and I would never ever recommend this place. To treat a potential customer like this when your in the wrong is absolutely atrocious.
