In reality more like a 3.5 stars. I've been by this place many times and I was finally able to give it a go. Rather than ramble on about ambiance, the service, the location I'll cut right to what matters: the food. I'm a vegetarian and as such I accept that my dining options are not as vast as those with unrestricted diets. However, Asian cuisine is generally very veg friendly and as such I dine at Asian restaurants probably more than any other type of restaurant. Unfortunately, Republic Ramen falls a touch short of what I'd call "Veg Friendly". The only option you'll have is the Vegetarian Ramen, which is OK because that is what I came in there for. And while the ramen was good (very rich, salty and tons of toppings) one dining option is not enough to make me a regular. It would be nice to try, say some udon noodles or an appetizer that isn't edamame.
Again, the ramen is good. And the price is fair. But would it really be so bad to leave the fish sauce out of a dish or two? Or to try using a vegetarian dashi instead of a fish-based dashi?
