The ambiance at BarMASA is spacious and modern. The food are very good, but a little overpriced. I had probably the same or better sushi for much cheaper. Of course, with the price tag, the presentation is very clean cut and pretty. I tried some of their sushi, their appetizers and their yakisoba. I did not like the yakisoba at all. It reminded me of Chinese cuisine's fried egg noodle with soy sauce.
The wait staffs are nice but they didn't check on the table too often. We were in a hurry and they tried hard to get our food out. But other than that, we needed to get their attention all the time.
It's defiitely a place to sit, enjoy, take your time to catch up and eat and such. So if you're in a hurry, don't come here.
