I've been to four shops: Miss Campus, Campus Night, Chocolat Kiss and Kurenai.
The first three are all similar to each other except for minor privacy and price differences. Chocolat was remodeled a couple years ago and is the most private and nicest in my opinion. I stopped going to Miss Campus a couple years ago because staff started getting nervous whenever I went in and seemed like they were trying to find excuses not to let me in despite the fact that I had been a repeat customer for years. Not sure what that was about but it kind of sussed me out so I stopped going.
Kurenai is different- there's lie-down booths and there's also an optional VIP room for extra where more things can happen. The girls are also dressed in kimonos here. The trade off is that the quality of the girls at Kurenai is a lot lower on average. My experiences there have ranged from okay to flat out terrible.
One problem I've noticed recently which I'm not sure if its a Corona thing or if its just cause I'm getting bored is that a lot of shops have significantly less talent and less attractive girls. As a result I feel that the stores are depending on their one or two top ranked girls more than ever these days. Chocolat in particular has basically been carried by their #1 girl (Sarina) for the past two years. Maybe things were always like this and I'm just now noticing, or maybe not.
How is the privacy?
