Shabu is excelling in many areas, and faltering in just a few. The most glaring area for improvement is in the service arena. They don't come around as frequently as they should and they keep the broth levels really low. This causes the items to stick to the bottom of the hot pot and burn. After your initial pot of broth, they refill it with pork or chicken broth - which is about the same cost as tap water - so they need not be so stingy with it.
My favorite items were the enoch mushrooms and pork dumplings. Everything else was OK, but those two items were delicious. I wasn't a big fan of the oval noodles, but my husband loved them, so we'll probably get them again. I also think it's important for the gentleman to tell you not to add too much to the broth before you start dumping large quantities of meat and veggies in... not after.
For four of us, it was $93 - and at $50/per couple, there's some room for improvement :)
