Is Latea better after their soft-opening? Short answer: no.
The most important trait of any food/drinks place is consistency. Sadly, Latea lacks consistency. Depending on what you order, the drink could taste great, or mediocre. Even if you order the same drink all the time, for the SAME drink could be delicious for one day, but nauseating for another day.
It seems like they're trying to train up new employees. Time will tell.
In summary, Latea is overhyped. Don't let the 5-star reviews fool you!
