My wife and I went there for lunch. We had never before been to a restaurant run by and for deaf-mutes. Basic sign language expressions appropriate to a restaurant are provided, making it easy to place our order. The waitress was helpful, too.
We found it to be a wonderful, inspiring experience, especially knowing that the income earned by this restaurant goes not only to those who work there but also to disaster victims elsewhere in the world (for example, most recently, victims of an earthquake in the Philippines).
