Confuse Friday and Saturday nights at your peril. Fuel is a rock and metal night, while Brazilian funk, Latin and reggae turns Tafod into a simple version of Rio on Saturday evenings. So unless you want to be a goth dancing the samba, or jive to MÖtorhead, pay attention to the line-up. Tafod, which is Welsh for tongue, is under the Nos Da budget hostel, so the crowds have that edgy feeling of here-today gone-tomorrow. So should your tongue go near or down some of the punters' throats, you're safe in the knowledge they will most likely be backpacked off in the morning.
