Keep your shoes on.

This was taken on the second day of our trip to Nagasaki.

We had seafood for lunch at a seafood restaurant, where I spotted this sign which was near our table. The sign was on a step to some extra space to eat in. I guess there have been some occasions where people, taking notice of the step, try to take off their shoes despite the fact that they're not expected to do so in the restaurant.

I didn't expect seafood would be that delicious in Nagasaki.
