The best thing about my recent experience at Soba was the service. The waitstaff were unobtrusively attentive and very friendly.
I highly recommend the chicken ramen, which has fried chicken, noodles, and a fried egg. I'm not sure how you can go wrong with that combination of ingredients. The true star of the meal was the dessert - some sort of chocolate mousse and pretzel stack that was really amazing and made in-house.
My only quibble is that some menu items are pricey considering what they are - I mean, $18 for fried rice?
