As I work in the vicinity, Sugisawa is one of my more frequented joints for business lunches and/or dinners.
To me, one would come to this place for their bento box sets, which are decently portioned and are also decently priced as well.
Whatever your choice of bento might be, Sugisawa's bento will not disappoint. From the katsus to the unagi, from tempura to saba, the food quality doesn't vary too much, even when the kitchen is packed with orders on a busy weekend evening.
Having said that however, what irks me the most is really down to the service level. While I admit Sugisawa is a small establishment, the service is a bit of a hit-and-miss affair for me. Oftentimes, especially when I'm seated outside, I find it impossible to get the attention of the service staff.
And when I'm seated on the inside? A number of times for dinners, I've been quite rudely chased out by the elderly lady staff, who is looking to turn the tables around faster rather than allowing me to enjoy my time in the restaurant. On one occasion, the elderly lady said to me and my business associate, "Can I clear the table now, I want give you the bill?". It was really a rude shock for me as I was in the middle of a discussion with my business associate, and while I understand where they are coming from, it must be noted that I'm not the only person there who is trying to talk business over a meal.
All in all, good food, not so good service.
