Mountain Sun Pub & Brewery Bar & Pub ·$$

This carefree place has a penchant for all things out of a bygone-hippie era which may seem a bit anachronistic, however the recognizable psychedelia and music make it comfortable. Even if you are not into that music or style, the menu is still worth checking out. Here the kitchen features healthy salads, sandwiches and a huge selection of burger options like the 'Black and Blue Burger', which is a pepper crusted blue cheese monster. On tap, visitors will find Mountain Sun's very own beers, don't forget to check out the 'Dark Side of the Sun' list which features tons and tons porter and stout.
