Since I live pretty close by and I've been to most of the sushi places in the area, I thought I'd pop in and give M sushi bar a try. The place just opened up a week or two ago, so they are still figuring out the logistics. The ambiance is really nice, its not fancy and its not a big restaurant; but it is well thought out. I liked the Japanese paper lanterns hanging from the ceiling. The service wasn't great; they only had one girl that was acting as the hostess, waitress, and busser for the whole place when we came in. A second waitress came in later before we left. But because the place is new and they're still figuring things out; I'm willing to give them a pass on the service considering it was just her and she was running around all over the place.
*FYI: their liquor license hasn't come in yet, so you can't get an alcoholic drink there for at least a couple weeks.
The food was pretty good. The sushi chefs were nice, and the fish was a pretty good quality. The rolls are reasonably priced compared to the other places in this area, and the chicken cutlet dinner entree was tasty. I'm a bit picky about my sushi, especially the quality of the fish; and M's is some of the better fish in the area.
I didn't notice any problems with the bathroom like one of the previous reviewers. All in all it is a nice restaurant and well worth checking out if you are in the mood for some Japanese food. I will definitely come back to try it out again, but I plan on waiting a few weeks until they get their liquor license and they get a few more staff.
