Hmmm....
I wasn't thrilled with our last visit to Sam Woo in Los Angeles, and frankly I'm not sure why we chose to try Sam Woo in Vegas. We ordered a chicken dish which was' meh', and salt and pepper squid which I generally love ... but not here: doughy, non-descript, under-seasoned. A waste of calories. On the plus side, we did enjoy wonton noodle soup, which was similar to what we order in our favorite Malaysian restaurant.
The service? Efficient. Not friendly, not solicitous. But it's the food that would deter me from coming back. Not the staff.
