The Kaz Bar is a great lounge right off the main lobby of the House of Blues. It's a dark, comfortable lounge with plenty of little enclaves to escape into. There are also multiple couches and overstuffed chairs to relax on while enjoying your drink. The drink menu was wonderful. I highly recommend the large "River" martini for $16.00. They also have a light appetizer menu available. The only downside is that they close at midnight so you have to leave the hotel if you want to continue your night out. Take a stroll to the bathrooms and check out all the interesting art work hanging on the walls.
