We arrived at 8:20pm on a Tuesday night. The owner/chef/server immediately seated us and gave us the menu. We put in our orders at 8:30pm. 20 minutes later we had to ask for our glasses of water again. By 9:20pm the fish & chips came out. At 9:30pm the udon. At 9:45pm we had to ask about the ramen as the rest of the table had already finished their dishes. It wasn't until 9:50pm that the ramen finally came out.
There was only one other table in the small restaurant with us, who also experienced and complained about the long wait.
The food was great and tasted very authentic, but definitely not worth the hour and a half wait. It's unfortunate because the customer service was good. But he was a one-man show: taking down orders, cooking the food, serving the table and handling payment, all by himself.
He apologized for the wait, but we would not be returning until there are some major improvements with the waiting time.
