Will TASMAC be open during Pongal??

I’m throwing my engagement party in ECR on Friday 17th Jan and I forgot to get alcohol for the same beforehand and now I realised it’s Pongal, everything might be closed and I might be in a fix. So makkale, will TASMAC be closed even on 17th Jan? What about the elite stores in VR/Phoenix mall? Where can I purchase alcohol from on or before 17th Jan?! Please help 🙏
