@stephen15 Hi Stephen. The location. My personal preference is that I dont fancy sitting there with all the trains going by making a noise, and having loads of people walking by all the time. At least with the Rock Pool Café, it is a more 'open' area and quieter, plus you can still see the trains go by if wanted. I hope this answers your question. Enjoy your sunny Sunday.
I think that I would prefer to use the Rock Pool Café. Just my opinion.
In addition to what @wriggler above said, I had a look in Sainsburys a few days ago and purchased a pack of Jam Doughnuts. There were Five doughnuts in the bag which cost me the princely sum of 65p. Now, call me disloyal to local shops, but why should I go to a bakers in the Strand to buy a jam doughnut for 65p EACH when I can buy a pack of 5 for the same price and which the kids enjoy ...
Good luck to all concerned. I sincerely hope that it is a success.
