Great downtown spot.
The Griffin is located in the newly revitalized Fremont East district of Downtown Las Vegas. Really it's like a two block area next to the Fremont Street Experience, but that's beside the point. This bar is awesome. You're not surrounded by arrogant club types. There's a few pretentious looking hipsters, but really everyone is just there to chill with friends and have a kick back time. The jukebox might be the best part of the place. Excellent selection of modern/classic rock and it's only a quarter per song. The bad news is it can take forever for your song to play. The drinks are Vegas priced, but not quite as bad as the strip. If you smoke, The Griffin sells cigarettes but at an ungodly 7 or 8 bucks per pack. This also means the Griffin is a smoking establishment, so be warned.
There are two rooms at The Griffin. The first (main room) is nothing but comfortable booths. There are also a few fireplaces/heaters that people can sit around. The bar is also located in this room. On a busy night it can take a few minutes to get noticed by the ultra-hot bartenders. I hear one of them is a suicide girl. The back room is a little more spacious. It has a few couches and comfy chairs for sitting. There's also a place to dance as a dj spins records. The crowd is mostly young, 20's/early 30's. I highly recommend it if you're not one for some overrated mega-club.
