A menu for my family

We are going to prepare a dinner for a family gathering tonight to celebrate the 80^th birthday of my grandpa.  His wife wants to eat at home because of the warm feeling. Grandpa loves eating fish.  My mother likes beef and my father prefers spinach than other vegetables. My sister favours meat and I love all food, especially dessert.  Here is the menu:

1. Sweet corn cream soup
2. Grilled steak
3. Steamed garouper
4. Fried spinach
5. Roasted piglet
6. New York cheese cake

Budget: HKD$750-$1000
