So bare with me, I'm sure this sounds a bit odd.
I'm starting up a business where all of the cooking will be done off-site. The actual store itself, will be like a 'showroom' of my products (sandwiches) like EAT (and to a lesser extent Pret a Manger) in the UK. It will also sell coffee.
I want it to feel very fresh and warm, but I'm concerned that it won't really smell very warm/fresh.
Are there any electronic options available that won't smell (like those scent dispensers they use in hotels etc.)? Is there anything else you could suggest?
