I had lunch in Saborsito only a few days ago, and whilst it was tasty and well-priced, the menu wasn't the most extensive and the whole place just seems to be lacking in atmosphere.  \nIt's popuar with the students from the nearby George Square and so it must be doing something right.  The staff are friendly and unusually quick to process tour order.  I had a cheese and ham toastie with a cup of coffee which was pretty nice, but not the most filling lunch I've ever had.  They do, however, have have a good range of delicious coffees which are all ethically sourced and expertly ground.  I just had their standard latte and it was great.  \nSaborsito, with a bit of livening up, could be turned into first rate cafe.
