Why did we dine here? – Orenchi is a very popular Japanese Noodle House that has been on our hit list for a while. They are a sister restuarant to Sumika in Los Gatos. The broth that they use is cooked for a minimum of 18 hours. It is made with organic chicken, Canadian black pork, and filtered water. There is a line much of the time. We had to wait approximately 45 minutes for a Saturday night dinner. They close up when they run out of broth, which happened about 8:30pm on this particular evening.
