In many ways there is great information in this book. It's a bit dry and a little dated but it is very thorough in terms of the information that it contains. i.e. if you want to start a sandwich bar then it is certainly a good start. It provides a worthwhile road map to help you get open. There is a lot of advice on the tedious but essential stuff like dealing with your EHO, insurance agents, surveyors etc. You even get little sections on stakeholder pensions and walkie talkies.
My issue with it is that it really the story of one man opening a sandwich bar. i.e. it is based on a very limited experience and very specific factors. The days of being able to open a sandwich bar (or a coffee bar) in the style of this are, in most areas, gone. The competition these days is ferocious and I know, from harsh personal experience, that you need to work really, really hard to survive out there.
So you may have a section on walkie talkies but you also only have a half page in the whole book about coffee and that's just some very cursory advice about the machines! A book with the title of "Starting and running a sandwich-coffee bar" is being somewhat disingenuous with the title if it only has half a page on coffee in my opinion.
It also singularly lacks any emphasis about creating something unique and almost completely glosses over the financial side of the business. The marketing sections are extremely limited too. You can see sandwich (coffee!) bars opening like this in your own town almost every year and they simply don't last.
To operate a successful sandwich or coffee bar you have to dig much deeper. You really need to focus on creating a reason for people to visit and you need to have a handle on your figures very firmly from day one. You also need to learn every marketing trick in the book and keep learning every day if you're to compete with one of the big chains opening beside you. If you rely heavily on the advice of this book the chances of long term success are extremely limited in my view.
But like I say there is some good basic advice there. I'd still recommend you have a look at it but I'd also buy at least five or six other books of this type as well. The two essential purchases for anyone who is even vaguely thinking of opening a sandwich or coffee bar are "Wake up and smell the profit" by John Richardson and "The E-myth" by Michael Gerber. Those are the two books that transformed my little sandwich coffee bar both in terms of profitability and also the ability for me not to have to be there every day myself.
And if you are thinking of opening a sandwich/coffee bar then good luck. But make sure you have removed your rose-tinted spectacles and have your eyes fully open from day one. It's a great business but a long way from being the dream-life that most of my friends think it is.
