This is the second time I have dined at Yummy Sushi.  The first time we dined here it was by chance; we were hungry and we're just cruising Lake Mead Blvd looking for a place to eat.  Had I written the review the first time, I would have given 4.5 stars.  The fish was fresh and delicious. We tend to get nigiri and sashimi only. The server was friendly and the sushi chefs too.\n\nWe had the same server and she is very friendly and nice.  Now, here is where it all goes awry.  We order a couple of hand rolls, it was good.  I love yellow tail, so I requested an order of hamachi nigiri.  The sushi chef prepares it and hands it to me while my man is away in the bathroom.  I look at it and it does not look like yellowtail.  I take one small bite and I can barely bit into it.  On top of that he tried to add something to the fish to make it more edible.  I still don't know what it was.\n\n My man comes back from the bathroom and I look at him and he says \""what is that?\""  I said, \""supposedly yellowtail\"".  My man takes a bite, looks at the sushi chef and says \""Yellowtail??\""  He only said one word with a question in his voice and the sushi chef immediately says, \""oh so sorry I give you better piece, I accidentally give you piece that was bleeding\"".  What???  I have been eating sashimi for 15 years now, my man a little longer.  We know good sashimi.  He tried to pull one over on us and I felt really insulted.  He shouldn't be serving that to anyone, even if they hadn't known the difference.\n\nShame on you owner and sushi chef! (slap on the hand)  I thought I had found a great place to have sushi in town, now I will have to resume my search.  I never mess around with raw fish, all it takes is one bad experience for me to scrap a place.  Your place is officially scrapped Sir!  I know I am a dissenting review and perhaps he was having a *moment* whatever. SCRAPPED!
