I'm a fan of Tampopo. I'm fairly new to ramen (didn't know what I was missing out on) but so far this place is my favorite spot to get ramen.
The broth is good (I've tried a couple different ones) and both the pork and pork belly are worth getting extra. The chicken is good as both an appetizer and an add on.
It's a very small space but the waiters have always been incredible attentive and friendly when we're there. It can be fun to sit by the kitchen and watch them work.
I'll be coming back!
