My go to drink is the honey black tea with grass jelly at any bubble tea place. Formocha is probably my favourite place to get a honey black tea.
The tea taste is very strong, refreshing, but not over-powering. The honey helps balances the slight zing from the tea. You can really taste the quality in their tea leaves.
This place is small but there are a few (four I believe) bar seats in the front of the restaurant.
There are many bubble tea places to choose from in this area and probably cheaper when it comes to price but Formocha definitely has the 'quality' you are looking for in bubble tea.
