This is a friend's favorite frozen yogurt spot, so I get dragged here from time to time.
The problem with Golden Spoon is that some of their flavors have a really artificial taste. Of the flavors I've tried, I'd put the banana, pistachio, and graham cracker solidly on this bad list. I don't know if it's just the way they sweeten it or flavor it... the aftertaste in particular is no good.
On the plus side, I find the toppings (especially fruit) to be fresher than other spots and the service is always friendly.
I would probably rate this place a 2.5 if it were possible, but rounding up to 3 is fine on the basis that if you know what flavors are good or are aiming more for toppings, it's a pretty decent place to get a quick fix.
