Blue Martini is sort of the Cheesecake Factory of bars. Don't expect anything exceptionally good. There is a vibrant bar scene and a nice patio. The bartenders are sloppy and inconsistent. Also, don't plan on getting a craft cocktail or any fresh ingredients. The food is edible. Prices are great if you take advantage of happy hour or industry discounts.
It's a fun environment but the bottomline is there are hundreds of places with better food and drinks around town.
