I'm going to be spending a day in Singapore on the way to New Zealand, I haven't been there for years. My friend says I should try the banana leaf curry restaurants around the back of the old Indian area. Are they all the same or does anyone have a favourite one, which is better, then the others?
Also thinking to buy a new camera, are prices still cheaper for cameras and electronics in Singapore? Any particular are to shop in?

Prices for electronics are not cheaper in Singapore than in the US, nor have they been for many years. If you live in Europe or the UK you may find the prices to be cheaper because of the VAT.

There is a restaurant called Banana Leaf in SIngapore that is often recommended here.

Years ago I ate at one called Banana Leaf Apollo on Racecourse Road. I haven't been to Singapore since 2001, so I have no idea if its still there. My hunch is that the food at all of them is substantially similar.

No, they are not the same! This dish is meant to be shared. 2 of the most popular are Muthu's and Banana Leaf.

Waiter, there's a fish head in my curry

One speciality of Little India is fish head curry, a uniquely Singaporean dish. It's one of the stranger-sounding and admittedly stranger-looking dishes around: no, you don't eat the head itself, but there's plenty of meat to be found inside as the head in question barely fits on a plate! Cooked so long that it falls apart when poked at, just dig in and pile up the bones on your table. Eyeballs are not eaten, but the Chinese think the connective tissue behind it is the best part of the dish.

There are two types of fish head curry in Singapore, Chinese and Indian. Little India's fish head places unsurprisingly mostly serve the Indian kind, which is usually spicy and hot. Most specialty restaurants are on or near Race Course Rd, conveniently located between the Little India and Farrer Park MRT stations.

* Banana Leaf Apolo, 54-58 Race Course Rd. 10 AM-10 PM daily. A well-known place for all sorts of South Indian food; no prizes for guessing what serves as the plate. Most visitors come here for the fish head curry, even the "small" size is enough for 3-4 and will cost you $18, plus $2.50 a head for rice, pappadams and dips.

* Muthus Curry, 72-78 Race Course Rd. 10 AM-10 PM daily. Muthu's has a respectable claim to coming up with the idea of fish head curry; now run by the founder's son, this shop continues to draw the crowds. Fish head $16-25 (''serves 3-4'').

I've found with electronics and things that they can be a little cheaper than NZ prices. For the same price you tend to get a more updated camera in Singapore that is a few steps ahead of NZ(generally the case!) this is always good
