Starbucks prestigious? Maybe in the 90s. I thought it was more like the McDonald's of coffee shops. Every Starbucks I've been to in the UK looks run down with peeling paint, dated decorations and uncomfortable "canteen" style furniture ... Filled with tourists and loud foreign students not to mention the dirty tables and rubbish all over the floor.
The ones I've seen State side look a bit nicer I guess.
I would hope for something else like a Costa or Nero as they are normally furnished much better and with comfortable seating at the least. Other than that I'm not an expert on the exact differences between them as I'm not a huge fan of coffee shops generally. All I know is that Starbucks always seems to be too busy, uncomfortable and dirty.
