I would love to give this restaurant a good review, but I'm not because since I sent a message. They haven't bothered to even answer me!!! I My mom and I visited this establishment and we really enjoyed our milkshakes. So we decided to go back again. When we went back they were closed due to the fact that they had fumigated. Well, we still wanted to have one of their milkshakes so we went back. We had another milkshake, supposedly the same as the first time, which was a chocolate milkshake. Except this time there was no flavour at all. It was thin and insipid. So we decided we wouldn't frequent them again, nor would we tell others about them. Then I thought maybe they need to know this happened, so I sent them a private message on Facebook and they haven't even bothered to respond
