BTW, This place is not at 207 Unity anymore. They moved to 1311 N. State St in January!
Dashi is awesome! How it works is you get a choice of "Toppings" (Chicken, Beef, Pork, Tofu, etc.) for you soup and that's how the price is determined. Then you choose from one of their HOUSEMADE Noodles (Ramen, Udon, etc.) and Broths. It's so fun because its completely customizable! I like Pho but I dont care for the traditional rice noodles. So I pick Udon (a thick, chewy noodle) to go with my Pho broth and top it off with all the traditional Pho accompaniments from their self-serve condiment bar (Basil, Cilantro, Jalapenos, Sambal, etc.)! Not authentic Pho but Delicious! On the second visit I tried their Ramen Noodle with Pork Shoulder and it was just as good. The Noodles were obviously made in house and they were cooked to perfection. I would recommend the Konbu-Bonito broth with a Soy-Marinated Egg. Again, its not like going to a little hole in the wall Ramen shop in Vancouver but its fun because its different and everything is super flavorful!
My girlfriend had a Chicken Steamed Bun with Coconut Curry sauce and we were shocked how big it was! It's the same soft steamed dough as your typical Chinese Hum Bao but it is shaped like a pita and is the size of a burrito! A little messy but very satisfying! We also tried the Chicken Wings which were A-Mazing as well.
My only criticisms of this place would be that it was hard to get street parking and it was also tough to get a seat because they were so busy. But we went on a Friday night so it might be easier during the week. Also, they have a great wine, beer, and sake menu. Unfortunately it is a little hard to read and is awkwardly positioned so you cant see it until you get to the register, which makes for a last minute decision. But I"ll cut them some slack because they just recently moved into this location. All in all, I would say if your looking for a unique Noodle experience and your not too much of a Pho (or Ramen) "purist", definitely give Dashi a try.
