Blazing Salads is a cross between deli and well stocked health food shop. Within a minute's walk of Cornucopia it's a good option if you're pushed for time or want takeaway.
I picked up a slice of pizza and piece of apple pie from there the last time I was in Dublin. Both survived 9 hours in a laptop bag admirably - the pics below were taken just before shoveling them into my gob and going through security at the airport.
The pizza was great, but much more quiche like than pizza. How it didn't get mashed to pieces in my bag I'll never know, but it's a testament to it's suitability as excellent picnic food.
The apple pie didn't look so great (which I'll put down to my handling rather than Blazing Salads' prep), but also tasted good.
I'll definitely give them another go when staying in Dublin next - I may even push my luck further and buy the day before for breakfast at my hotel.
