I always stop by Mr Tea when visiting Vegas! The staff is always sweet and I believe they offer a 10% off on the Yelp business page. Very clean and cutely decorated. They offer the light bulbs, ( are decorated with different faces you can choose from) small, large cups and half and half flavor cups. The tea is just the perfect amount ; not too bitter/strong. One time I was with a friend and they messed up twice on the order but insisted on remaking it until it was right, So sweet ! Great boba and great service.
