individual can only do that much. for such an location, it needs the synergy of many shops. if only like a handful out of the 20-30 shops are good. then, it will not attract a good amount of traffic. it will however, still get those people looking for those good shops.
"A & P" is what ah?
there's one classic example i can give on synergy. Sim Lim Square. rundown place, bare. boring. but hell, that's the heart of the consumer electrical products market here. 2 years back, some of the shops left SLS n went over to Funan to open there. n long story short, they flopped. and had to move back to SLS. (likewise for some that open a branch at Funan, then close it down.)
incidentally, some shops at Funan uprooted themselves to move over to SLS.
cost of material has seen it's most crazy rise this year. hence the record inflation figures of 6-7% (projected). real person experience is higher.
on the decision whether to increase prices will have to depend on price elasticity. you go up by A1 amount, have would be the percentage drop in B? you go up by A2 amount, what would be the drop in B2? (you would know better lah, since you are in the business for how long? 8 years?! .P)
one thing that's universal and that you can apply is to control/cut cost.
ie: less wastage of food while in prep
ie: smaller portion.
it's reported in the papers that some products like JAM bottle have reduce it's volume, while retaining the price. likewise for some drinks etc.

personally, i was there at the "New youth shopping area in Suntec" a couple of times (weekday 6pm, weekend 2pm). it was really quiet n dead. was quite puzzled because just a 5 minutes walk away, those carrefour n the main lobby area is packed with people!
