In appearance Sekisui is a typical Japanese restaurant. Clean, lots of wood, perhaps 20 or so tables and a nice sized sushi bar. There's also a back room with a bar that I've never been in; it seems unused even if set up for use. Service was pleasant and attentive. Wheelchair access is very good and there's a parking lot in the back. (A couple of members cars were broken into back there at night at the last club visit five years ago, but I always park there without problems and there were a lot of cars there too.)
Sekisui is a small chain, including a sister restaurant in Clayton - Sekisui Pacific Rim (all the sushi - with some exceptions - you can eat for $25 on Tuesday evenings!) - but it certainly doesn't look or feel like a chain. Kenji is in charge, and when he's "on" it's as good as anywhere in St. Louis. Now, as for the club visit:
A nice size group -- twelve -- were on hand. Solicited opinions were all over the place, from thumbs down to excellent. A couple of people complained about the white tuna, a couple of others thought it was great. Appearance of the food, while not very adventurous (try to imagine, if you will, "St. Louis" and "adventurous" in the same sentence), was very pretty; neatly and precisely plated - the rolls as well.
My meal was excellent. I got nigiri only, plus green tea and a dessert. The rice's texture and amount of seasoning was spot on, the fish very good to excellent. OToro was buttery and medium flavorful, with what seemed like just the right amount of days of waiting on the tuna before service. Shrimp was small but very tasty with a wonderful texture. Tea was a little strong, but that's true of most places. Ran, the founder of the group, also reported an excelllent meal. Scott, one of the original members, reported a very good meal.
In spite of the apparent gliches with some of our group's meals I still highly recommend giving Sekisui a try. If you're local and you go, ask for a frequent diner's card which will note what you spent on the meal with a percentage listed. After the amount of the percentages reaches $10 you can use it towards your next meal.
