The venue itself is good with great facilities and very clean. However, the surrounding bars within the venue were run very poorly. Staff did not have a clue what they were doing. To charge the prices they were, they provided a shocking service. Each person that queued at the bar for refreshments took about 10 minutes to get their drinks after ordering them.
Not environmentally friendly either. Bottled drinks were poured from plastic bottles into plastic cups! Work that one out. Such an overuse of plastic.
There are no bars, pubs or restaurants in the surrounding areas of the O2 arena itself either.
Very disappointed.
