there is an excellent fish/chips place called Fishcoteque.

Dipende dalla zona, in alcuni punti ci sono dei locali aperti di sera con un po' di gente vicino ma, per il resto, è un posto un po' buio e deserto di sera. Molto meglio fare una passeggiata di giorno.

There are lots of hotels nearby and lots of separate public parking. Rather than fight the London traffic I would do what someone else has suggested: stay out of town (not necessarily as far away as Colliers Wood) and take the tube to Waterloo. South Bank is 5 minutes' walk from the station.

There is free WiFi that is better near the eye and there's one in the southbank centre, also McDonald's and neds has WiFi, I think there's more but these are the ones that come to mind
