There is also a fleet of "special hire" taxis or '4+1's' that carry you wherever you want. They are substantially more expensive than the minibuses. You'll recognize these by the yellow stripe down the side. They squeeze in 4 passengers heading in the same direction.

Regular taxis will pick you up if you call. Rather use these if you're travelling in a group of if you're out at night. Always confirm the price before you set off.
