i went there when it first opened.... sorry to potong steam but i do not have good reviews about it.
they charged almost like hotel rates, air con too cold and i feel so isolated and anti social after going there.
hahahaha maybe because i went there with 5 other friends and they gave us a corner "room" which was quite spacious. We had to talk softly and there was like random waiters passing by our "cave" every 5 minutes, as if they are checking us out. maybe they thought we would have an *rgy there? geeze...
The pricing is ridiculous.
great concept you said? i would a creative concept.
they do have smaller "caves" for couples but hello, i would suggest to go get a room then.
why pay so much for drinks & food (which is not very delicious to begin with) and cramp up in the small space with your partner and have to talk as soft as possible (or i would say, make as little noise as possible)...
silly really silly... but it's no harm trying.
no harm visiting the place to just to kill your curiousity and to experience how it's like to dine in a cave... manmade cave that it.
