Dear Ms./Mr. DonalPump. Thank you for choosing La Moi Plant-based restaurant as your dining place and leave us your feedback. Please be kind enough to open up with us, this is a tax principle by Vietnamese tax law that we always comply with, and you will find is normal in any official business point here (8% to be exact, depending on the government). Please notice, that we no longer have the 5% service charge, it's not in your final bill, and that's why we do have to charge for your wet tissue if you using it. The dry napkin is free, please ask. We understand from you that our pricing is different than a few other restaurants, but please notice that our product uses organic, fresh ingredients that are prepared daily on-site from Vinamit Organic. Once again, we would like to thank you for your constructive feedback, and for enabling us to share our concern with you as a valued guest. We are looking forward to hearing from you, and all the better, to welcoming you back to Lamoi. Very best from all of us, Lamoi Team.
