Hi Limay,
We had a few small scale gatherings for my hubby's family, my family and some of our common friends on 3 different occasions, on 3 different weekends. We cooked.
The first session was fun, becos that was the first 'party' we were hosting at our new place, the second one with our friends is not so xiong, becos it's potluck, but by the time we have the third gathering, we were totally exhausted even though each is a week apart. We had wanted to cook for our official housewarming party, but gave up the idea. It's very tiring, and like what carol says, there's alot alot of grocery shopping, planning (of what to prepare), cooking, cleaning and washing (after the gathering).
Carol,
I am having my housewarming this weekend. Caterer is Jack's Place. Was not recommended by to me by anyone, but we quite like the tea reception menu. Will let you know if it is good.
