A restaurant opening in Tokyo next month plans to offer a “naked” dining experience, but only if potential diners meet a weight requirement.

The Amrita restaurant, will require diners to check in their clothes and put on paper undergarments provided by the restaurant, AFP reported.

The restaurant cautions would-be customers to avoid making a reservation or coming to the restaurant at all if they are “more than 15 kilos,” or 33 pounds over the average weight for their height.

If a guests looks like they are carrying a few extra pounds, they will be weighed and if they are overweight, entry will be denied. According to the restaurant, those who made reservations, but were refused because of a few extra pounds, will not get a refund, AFP reported.
