This establishment is a perfect example of how LGS’s should be. Super friendly environment and the everyone who works there are extremely professional and knowledgeable. Everyone is very welcoming. Plus they got tons of cool inventory in stock. The store is really clean on top of it.

Cool place. Friendly folks. Singles are competitively priced. Literally to the point of me checking new inventory every time they restock.
