The last time I was there, the bellagio had it at the high dollar video poker bar. If you go sit at the bar and put some money in the machine you can probably order a glass and they'll comp it. I'll leave the ethics of that up to you.
Didnt go for the Hirsch. Went with a huge pour of WLW and it was amazing. They did have the PVW 15, 20, & 23 but ive tried the 20 and really wanted to try the WLW. It was everything I like in a bourbon - high proof, hot, and a fantastic finish. It lasted me through the whole dinner and was an excellent pairing with the steak. Best bourbon experience Ive had to date.
