HELP: wedding venue advice


Am a Q1 2024 BTB, and currently researching on venues for our wedding lunch banquet. However, we're totally clueless how to go about choosing one, hence would appreciate advice and past experiences!

To start, we have shortlisted 3 venues: Ritz Carlton, Raffles Hotel, Fullerton Hotel. Our top priority is the food.

Some questions we need advice on:
1. How early in advance should we book our venue? Google says up to 18 months, but 2024 rates aren't out yet which I'm thinking could be because of the GST increase (?)
2. Which of these 3 venues provide the best chinese wedding lunch?
3. Service of the staff? Overall experience? Value for money based on packages?

Appreciate the input!
