Chili crab is one of the most well-known dishes in Singapore, and the chili crab at Jumbo Seafood Gallery is among the most famous.
The crabs can be prepared in four different ways, although chili is the most famous, followed closely by black pepper (which is amazing, too).
Crabs can be expensive, so be prepared to shell out some money; however, the money is well worth it. Make sure you order some fried mini buns to go along with your crab so you can sop up the sauce.
There are several locations of Jumbo around Singapore. Because of it's popularity, it is usually quite busy, so, if you can, make a reservation in advance.
