any ideas of gd quality food but must be halal because i want to invite my malay colleagues over for my open house...buffet spread???

There are a list of food caterers that you can find here. http://www.foodline.sg/caterers/halal-caterer?sortBy=Customer+Ratings I had personally tried Elsie Kitchen http://elsiekitchen-px.rtrk.sg. I like it v much as the portion is generous and te taste is good. I specifically like their white bee Hoon and honey grazed chicken. They never fail to amaze me.
