We had our pre-wedding photo taken there, their service is good, but the trend and photo editing is a bit out of touch. But if you are not fussy and particular about that, they do a decent job.

Did not run into the issue of "You need to top up for this dress/gown".
We have the freedom to choose whatever is on display on the rack, if you are in the season where a lot of couple taking photos, the "ideal" dress for you might be taken, which is not on the rack, that's all.

Overall, it was pleasant.
