I recently got myself a few boxes of Nutrabolic's Isobar fairly cheap. Personally did not know what to expect in terms of taste. It is actually really good. Chocolate Peanutbutter is an amazing mouth watering flavour. Unlike other protein bars, this one does not leave you dying to drink water afterwards from having a hard time to chew it. Biggest difference between isobar and other protein bars is that most of them will do a better job at filling you up and killing your appetite whereas with the isobar i found that i would still be hungry not too soon after. Although, this attribute makes it ideal for bulking when you need the extra calories, protein, fat, and carbs.
