Only been on the ground floor at SOS for breakfast (twice) which I thought was ok! nothing special but ok.. there was something I liked about it which was the buzz of lots of people in a big place enjoying a good sized full English breakfast which was reasonably priced. The seating was a small wooden stool with no back support which was very uncomfortable to say the least. I enjoyed the proper mug of tea with the tea spoon left in,and the bacon was thick cut but I would have liked it a more crispy. The waiting staff where nice enough but if I may say a little scruffy in those horrible black screen printed T.shirts. Would I go again? yes of course it's ideal and the breakie sets you up for all that sight seeing after. I love the area around Smithfields and SOS fits in well and I can't wait to go back again.
To sum up if people are queing up to get in for breakfast then they must be doing something right!!!
