I've been here a few times and have had a good impression of the food but this one time is outstandingly bad. Today (08/08/16), I came with my family and cannot deny how the food quality has decreased significantly. A hot pot was ordered and the soup came sour and not how we remembered it use to be. The mushrooms were not washed and we had to wipe the dirt off with napkins. The quality of beef is also not good. The tea I ordered came lukewarm and I had to ask them to heat it up. I ordered some cold-dish appetizers which all came near the end of the meal. The salad I ordered came with a 'ponzu wasabi' dressing which honestly just tastes like soy sauce.
I have had very good experiences here previous to this one but I just had to mention that today was especially terrible. Not just with one item but with every single one.
