Unless things have changed (which is possible as management changes frequently), scarletts is just another clip joint, similar to tengo india, elites, atlantis etc.
Perhaps it does have new management, i know it was closed for a time, but if going there I would proceed with caution.
Keep in mind when going to strip clubs, december (especially mid december) is probably the worst time of year to go to tico places, as the 13th month salary, the aguinaldo, has just been paid to all costa ricans, and of course they are riding high on the hog and spending that money. They will typically be much busier than normal.
January on the other hand is the best month to go to a strip club in costa rica, as no one in costa rica has spending money during that time. You can find great deals from both the clubs and the girls during that time.
If you want a chill place, I would recommend Texas, it is a little more expensive than pantera rosa, but it has higher end facilities. But it is not a clip joint like hollywood, tengo indias etc. Drinks for the girls are about 3-4.5k colones each, and i believe sex in the normal rooms at the back (girl willing) is about 20k to the house, and 20-25k or so to the girl. It has been a while since i've been there, so prices are just guesstimates.
