Soba is a nice place to go for dinner, but I probably won't be coming here again. The food is pretty good, but paying $22 for ramen when I could go to Ramen Bar for half the price is just not very appealing. The pricing is comparable to Legume, but the food is far less unique. Also, the flavors were a bit bland, though I guess for a "fusion" place that is normal.
I will say that the ambience of this place is amazing. It is dim, but not too dark, and all of the furniture and decor is chosen with an eye for modern elegance. The bathrooms are beautiful and well-maintained (hey, bathrooms are important in a restaurant!).
All in all, a nice place to take a group of picky eaters who won't enjoy the less-traditional establishments. I would recommend it for business meetings.
