Thanks to all for the input.
We went to Saint Andrew's. It was cool. Even though we're muslims,
we find the idea of getting married in a quaint little church very
sweet, so we fantasized about that in the prayer hall. It's a
little sparse on the inside, maybe I was expecting more grandeur.
But the exterior is still very pretty to look at nonetheless. All
we did was talk softly in the prayer hall. Doesn't sound like much
but it was my fav part of the date. Went to the other cliched
places after that (Stamford, Esplanande, Suntec blablabla).
The church was a unique experience!
