Hi Lynette,
You would have to confirm with the tour operator but they are very flexible as I believe it is run by the tour guides themselves. We were fortunate enough to have a guide to ourselves who was more than happy to meet us at our Airbnb accommodation, so I don't see any exceptions to this. Again, it's best to check with the team themselves - they're incredibly helpful.
My partner and I did the Foodie Tour so all our stops were food related. We visited the local markets and sampled sashimi as well as local vegetables as well as meeting the friendly vendors of those market stalls, visited a yakiniku 'comfort food' restaurant, a knife shop where we were fortunate enough to learn more about the blades they use for slicing tuna, we stopped for lunch at a sake bar where we sampled three different types (the cups were VERY generous for samples) and after lunch we were led to a Michelin star - takoyaki stall - which was amazing and delicious!
All in all it was at least 5 hours of exploring and learning more about the Osakan food culture and for a reasonable price of about $150 AUD for the two of us!
I will absolutely be taking this tour again and switching some options up next time we visit!!!
