Thank you so much for your feedback. We are truly sorry to hear that the aroma of our ramen caused you such an unpleasant experience. At our shop, we prepare our soup in large, consistent batches to ensure quality control, so hearing about this "sewage" smell is a shock to us. We have one sincere question: Why was this not reported to our staff on-site? If it was that bad, we would have wanted to investigate the batch and stop service immediately to protect you and other customers. We are deeply sorry if the atmosphere of our shop made it difficult for you to speak up at the time. We want to make this right. If you can provide your receipt or proof of payment along with the date and time of your visit, we will issue a full refund for your meal. Please contact us directly at [arrrtvt@gmail.com］so we can assist you. Thank you for helping us improve.
