My ratings are based on food, since I had tried that here before.
Home wok was the first place in G I found boba. But they didn’t have tapioca ready at the time (she said it wasn’t very popular and to call ahead 2hrs and she’d cook some :P). Still the potential was there, even if they only did the milk tea flavor (boring!).
The food was good, but its a takeaway place rather then somewhere to try and eat. But as I am trying to flesh out the secret locales of boba for the UK, I thought I’d highlight everywhere I have found it (so it’ll be easier for anyone hunting around nowadays) :)
