Had a dinner with the family (of 4) and I have to say this is the worst experience/customer service We had ever had in a restaurant. It's hard for us (me, hubby, two kids 13 & 10) to criticize or complain since we always teach our kids to think of others perspective and situation before judging or complaining but tonight's experience was just too hard to excuse.
We arrived for dinner out, it was busy but not any busier than other places we eat out. We got to our table but thing got sour pretty quickly. Long story short, we waited for good 20 minutes as the 4waitress proceed to sit and serve others (5 tables) that came later than us. I figured they were busy and forgot that they didn't take our order so I finally flag one of the lady taking order of the table near us that we too needed to order. Quick apology and she took our order. However when we finally got our food, especially the Sashimi dinner plate, we were starting to feel bit annoyed. The plate seem to be thrown together in a rush -missing it's basic condiment of ginger and wasabi to name a few. It took us another few minute to even get them. Food overall was average, sashimi had fresh tuna but dry scallop. Other pieces of fish were thin -last end piece? and tasted watery mush. For the price (most expensive dish),this was a disappointing but we just told ourselves "to get a seat at the sushi bar" next time. Even up to this point, we try to make the best of it!!
DO YOU KNOW THAT during our entire meal, not one of the 4 wait staffs check on us nor cleared the appetizer dishes that we set /stacked aside as our main dishes were cramping our table? Wait staffs were busy taking new orders and checking on other customers...my husband joked that we are invisible to them.
Still we were trying hard to be positive, telling the kids that it's busy day (Thur )and the waitress must be having hard time keeping track.. Trust me, both me and my husband had worked in a restaurant, so we tried to be sympathetic. So we decided to eat quickly and just leave. We once again had to flag (raising hand etc)to just get our bill-mind you , we were sitting at our table for a while. Finally, a one of the wait staff bag our left over and left to get our bill. So here is the FINAL RUB...we waited another 20 minutes for our bill. Why wait so long? We were still trying to be sympathetic as they busy themselves clearing and taking in new customers! After all, one of the waitress finally cleared the table and we asked for the bill again!
Our Poor kids were getting restless by now so hubby took them out while I waited for the bill -trying to get the waitress' s attention again. OVERALL we spend more time waiting on the restaurant 'a staff than actually eating the food. DID I MENTION NOT ONE STAFF CHECK ON US NOR FOLLOW THROUGH WITH A BASIC REQURST -taking order or getting the bill to name the very basic?? Frankly, this restaurant is moving toward Quantity ( focus on getting their tables full ) vs Quality (service/food). The few tables that the Waite staff focused on seemed to be regulars... Never coming back nor recommending it to our friends & families. I am sure the business will care less.if we came back...after all we are just one of their many. Nevertheless, I just had to speak up.
