At Wheatberry cafe prices for party as follows
Adult buffet menu P350-475 per person with refillable drinks
Kiddie plated menu P165-200 per person
You can have them costumize menu to fit your budget. Email them, they reply promptly and once you've paid down payment, Nora is super nice.
They have free swags to decorate stage and free 12x16 cake for min of P10,000 and they also have free sound system, floral center pieces for tables and wifi. They offer stations like candy buffet, ice cream buffet, dessert buffet, etc. They also have entertainment but they allow outside suppliers without corkage UNLESS electricity will be used.
So far, smooth transactions with them. My daughter's party is still in March though so I can't give feedback about actual party but food was good the last 3 times I went there to taste the food.
