We went there for lunch as a group of 8 not knowing that they don't take reservations and that wait time would be 45 minutes before our group could get seated. They gave us a pager a-la-jackastor style. Though really there was no place to go other than the shangri-la lobby.
I ordered the ramen from the menu - seemed like one one of the logical choices. It was around $15. It did not disappoint - the noodles, ingredients and broth were good, however, i think you are paying for the ambiance when you pay double what you would otherwise at any other japanese ramen place.
We also ordered the steamed buns - $9 for 2. Tasted good, but pricey for what you are getting.
Ambiance was nice, very tight, packed, but modern. Service was adequate - food came in a reasonable timeframe. Location is convenient.
I can't complain about the quality of the food or the ambiance, however you probably don't get as much value for the price and the experience was not earth shattering as you would hope.
