Here on a Friday early afternoon with very little people in line (relatively). Yet I've waited over 20 min to order as the waiters waste time explaining to everyone what the specials are and chit chatting with random individuals. I'm still in line.
edit: after ordering, I waited for 10 min for the four baristas (not including the cashier) to make my drink. they seemed inexperienced and under coordinated, always pausing to fiddle around. with the slow ordering line, they were at most making order for one other person. It still took them so long.
Shape up, Gong Cha. Your decor and menu oozes Chatime, from which you obviously have taken inspirations from But your slow service makes you seem like rusty amateurs. I'm used to the fast and well coordinated service next door, which has an even narrower kitchen than you.
I'm only giving you a second star for the opening week free drink.
