Food: Come here frequently for late lunch and dinner lately. If you're a vegetarian note that all their soups come with meat broth. When you order all soups you can specify your meat (lean, medium, fat) and your broth (light, medium, heavy, which is the amount of oils I think). I usually have the shio ramen, light broth, with either lean pork or vegetables-only. Both are excellent. The pork option is well balanced with some very nice tasting pieces of pork and a good amount of vegetables (and I think egg as well). The vegetable option I especially like as I would say it is the largest and most generous ramen & vegetable soup you will find anywhere in Vancouver. Tons of vegetables and the same great tasting ramen.
Service: Good, but the waitresses sometimes don't smile much, which I partially understand because it is always crazy busy almost any time of day. Always a long line-up outside, expect 20-30 minute wait at least to get in normally and another 10-15 minutes for your food to come, but I keep going back because it's worth it.
Value: Great value. Large portions and great taste.
Ambiance: Okay ambience, customers always seem happy, but the environment is very sparse. Clean, very basic white walls, simple chairs and tables, etc. You come here for the food and bring your friends, but you don't linger afterwards.
