"Beware if you questioned checkin desk, act as if they don't need you you need them! Most unfriendliest poker employees in Vegas, no competition downtown and it shows!, smoky, dirty and crowded , welcome to poker Walmart !!"
I fully agree on this Review, checking desk the asian male was very like you said and unfriendly (female at the desk was ok), in Addition to what you said the Room itself looks worn out. Some Players are screaming to each other (i guess locals) from different tables at the Time i was visiting the GN. Dealers are very unconcentrated and won't pay much attention. I assume this Place has seen way better times back then in the early 2000's. This was the only place i felt unconformtable playing poker in Las Vegas. Won't visit this Casino anymore.
If you're new to this town i suggest playing at the strip in Resort's World.
