I will preface my review by saying I'm from Southern California, which has a plethora of boba (bubble tea) options. So I am reviewing this in relation to he boba I have back home. The bubble tea is terrible. The boba is so soft it doesn't have the characteristic chewiness of tapioca. The tea (I got green tea with normal sugar) was super watery and didn't have much sugar, basically tasting like water.
The price was very high for the quality of drink I got. I am not sure if other bubble teas nearby charge a similar price but $5.50 was too high. The drink is probably a $3.50 max drink. For reference the Quickly store, which is a low price boba chain in SoCal has a green tea boba that is probably around $3.00 (USD) that tastes better than the tea I got at Bubblemania.
The environment is dingy. I get that it's a hangout but you can make it a cool, young, hip environment if it didn't feel so dirty.
I think ultimately the issue with the establishment is there is not enough competition in this food space so they have no motivation to improve. That may be a major contributing factor for their lackluster drink offering.
