I really like MegaMart at Landmark, the staff are all really nice and the guys on the meat counter know what they are doing and will prepare meat for you. It is by no means the cheapest though. Carrefour is good value, has good selections and friendly staff but the lighting is too bright and it's always too hot in there. Also, there is always a scrum around the electronics department, makes it hard to get served when it's busy. Giant has the freshest produce and is the best value and is rarely busy but not such a good selection of international foods. I agree about Lulu and also it's too cold in there-wear a coat if going!
