On 3/10/2025 Jessi Mini had this to say:
Very helpful place to shop! It's my go-to when I'm looking for a gift for my husband.

On 2/23/2025 Gerardo Garcia Campos had this to say:
Store owner stayed late for me and didn’t pressure me into buying anything. I tried on almost a dozen pieces that were at or below my price range and he was knowledgeable on each one. I only wanted a jacket, got one I liked below budget and ended up buying a shirt too. Second time buying at TGS, will be back.

On 2/4/2025 Jeremy Cavaletto had this to say:
