Went to SW on a weekday to celebrate a friends birthday. Staff was very professional, however when asked a few detailed questions he had to leave he table and return with an answer.
There were always several bussers and water fillers on hand and came at appropriate times to service the table. The room is also very modern with high ceilings and large windows which look out to a patio and waterfall.
Needless to say my expectations weren't completely fulfilled dining here. I was surprised at not the biggest selection of cuts (maybe 4) for a establishment specializing in steak.
My rib eye was seasoned very well but I wasn't given as much of a kick of flavor as I hoped for. As any typical steakhouse, the sides were expensive and small. I was really impressed with the dessert selection and I noticed other tables ordering some very creative things for their large groups!
Needless to say it wasn't bad, but in my opinion not completely worth the price. With so many other options in Las Vegas, I would most likely spend my dollar elsewhere.
