Hi there, think the shop you are talking about is Magic
Castle.
Its not exactly at Bugis itself but just a 5 mins walk away to
Shaw Towers, on the 2nd floor.
Its not closed down, cos I was there just last week. Their
service is very good.
The other one is at Pennisular Plaza 4th floor. Its quite old,
but the owner is very experienced.
There are others but these are the ones that I know off that are
the nearest to Bugis.
Hope you will find what you are looking for there. Cheers!
