The ramen are good, they have a big selection, and they offer low-sodium broth. However, they are also considerably more expensive than, say, Rayaki in Cherry Hill (e.g., Curry Ramen is $10.50 at Rayaki and $13.95 at Rai Rai). By big selection, I mean that Rai Rai has about 30 different ramen, while Rayaki has abut ten. Rai Rai also has non-ramen meals (including a half dozen Taiwanese dishes), and more side dishes.
(Basically, Rai Rai is more a real restaurant, while Rayaki is a quick ramen place.)
I had the Butter Corn Ramen–definitely had a butter flavor, which seems very non-Japanese to me, but there it is. Mark had the Chicken Katsu Curry Ramen (the Katsu comes on the side), also a good flavor broth. We both got low-sodium which meant the broths were not overpowered by salt and had a more delicate flavor than is common.
Like I said, the ramen were good, but pricy. (Mark compared his to the pho he gets at Pho Da Nang–a big bowl of soup with grilled pork on the side. The Pho is $7.95.) It’s possible that someone with a more refined taste than ours would say Rai Rai is worth it.
This is apparently the third in the chain (others in North Brunswick and West Chester PA).
(They have two take-out menus; the one with Kanji seems to think that yellow print on a white background is readable. It isn’t.)
