Short and sweet: does not describe Raku. If the line is to the door (and I'm talking like 8 or 10 people) it will take you an hour to be seated and another 30 minutes to get your food.
Does the food itself save the Raku experience? No, it was mediocre at best. Not worth the price tag at all. The coffee jelly "tastes like tiramisu" was just bland and tasted only slightly like tiramisu. I would have infinitely preferred real tiramisu. I ordered the souffle, which did have some tasty cream but that's it, the rest of it was mediocre.
In short Raku is an expensive dessert place with a long wait and mediocre desserts. It is very cute and pretty though. A good date place if there is like 2 or 4 people ahead of you. Even on a first date waiting an hour standing in a tiny line would be a mood killer. 15 or 30 minutes though is OK.
