I've been going to Monta for a few years now. It's such a nice place with delicious Ramen~ The staff are always nice and helpful even though the store gets busy almost all the time I'm there.
There is a waitlist since it's a popular place, but also has a small room. It's worth the wait though. You can always get Boba next door called Kung Fu Tea while you wait or grab some afterwards.
You choose the type of Ramen you want and you can add topping for additional cost. I always add Nori(Dried Seaweed) and Nitamago(One egg split in half. Depending on the type of ramen you want the noodle will either be thick or thin. I enjoy either one in my opinion.
