I've visited both restaurants in recent weeks and had not seen it reported here, but both have ramen on offer. Ippuku has a mini ramen for $7 that is indeed a modest portion, I would guess 40% the size of a bowl at more conventional ramen shops. It's a chicken based shoyu stock, very kotteri, if I am using that term correctly. Just say thick. Excellent base flavor, though I might dock a few points for it being very salty even by ramen standards and the shoyu at least on that day coming out with a little bit of harshness.
Kiraku has a basic shoyu ramen for $9. If you order it they serve it to you after everything else you order, as a kind of cleanup hitter. Toppings were sparse, 1 slice of plain but tender pork, naruto and I think spinach. The broth at first sip seemed very mild but built up to be a quite satisfying bowl, the stock is indeed light, but with a balanced layer of shoyu and pepper flavor on top of the light meat stock. Honestly I w not sure if it was pork or chicken based but it is clearly there.
Noodles at both places were cooked well and good quality. I would say firm but not hard. I assume machine made from an external vendor.
I would order both again.
