I here been coming here ALL the time for over a year. We have definitely had a few service issues (hence the 4 stars) but the food is BY FAR the best ramen in Tempe, probably the valley too ?
Service: once we waited literally 1 hour for our check. Our waitesss left without telling us and then we asked someone else for it (15 mins in) and then they forgot (?) and then we just kept waiting. We're kind of awkward I guess ? we started timing it at one point because it just got ridiculous. No one came to talk to us! For an hour! The girl eventually remembered and brought it and apologized but didn't give a discount or anything? Not sure what's normal but she just said sorry and then we left. Other times the waitstaff have just been inattentive and even rude. I would say 30% of the time our waiter makes us uncomfortable or does something janky but generally it's okay!
Food: pork belly is pricey but it is worth it! I always also for the moister stuff (once it was so dry I couldn't eat it so now I always ask). I get the build your own with Paitan and Pork Belly if you aren't sure what to get-- just get that. I always ask for chili oil and then basically dump it on if you're into the miso flavor, I also recommend the miso hungry, with pork belly if you are into that.
We've only gotten sushi once and it just okay. I would stick to the ramen tbqh.
