I've gone twice - the weekend they opened and then the next weekend. I had to stop myself from going a third time because I could sense a snowball effect happening (both the fear I might start living there and the fear of becoming rounder and rounder in the mid section).
Went to Japan last year and fell in love with kyushu/hakata ramen. Cherryblossom Noodle Cafe's is closer to what I had in Tokyo (though only half as good), but this was still very good. Got the Republic ramen which came as a nice big helping, piping hot. The noodles were done perfectly - not overdone. The pork the first time was super! I could taste the ginger and the pieces were large and lean. The second time I was disappointed in the pork - it was a smaller portion, fattier, and less taste. I did fear they pulled out the big guns for opening weekend and won't be the same from then on. Guess I'll have to go a third time to get a good average.
I agree with others on here - skip the gyoza. I'm a huge fan of gyoza when done right, but these were greasy and thick with no dipping sauce if I'm remembering correctly.
Oh - and yes, the look is modern but the benches have a bit of an unfinished edge. I thought I was going to get a splinter. Look out for this or opt for the high top seating.
