Went here for the first time with my family today (labor day -- so yes, they are open). The waiting time wasn't so bad for us but am sure it can be a pain on most days when they are REALLY busy. The waiting area isn't large either so sometimes you would have to wait outside if your a big party of people wanting to dine in.
When you come in and would have to wait for a table, they make you write your name and the number of people your with (or they write it for you) in a clipboard next to the door. I think that's very efficient on their part.
But sadly, this place was "just okay" for me. It's not something I would constantly go back for but it's not bad to have either when you just want some ramen in your system especially if your in Mississauga.
I had their Karashi ramen and it was alright, not a fan of the broth but I guess it gets getting used to. The other dishes we ordered are gyoza (my family devoured it), karaage (it was decent, not the best I've seen on a plate), yakisoba (it was decent), Katsudon (decent as well), and a vegetarian ramen that was good according to a family member.
Staff is extremely nice and the place is decent. Very casual indeed.
In conclusion, I would come back here but not anytime soon. It's not that bad but it's not on one my top choices either.
