Unless you're a southsider who wants a day out and has more money than sense.
In my experience, this is an almighty rip-off. I recall, last year, getting a small punnet of chips with a few bits of chicken in it for €7. And that was the cheapest item on offer. In addition to this, you have to pay €25 just to get in.
To sum up, you pay €25 to get into a field where you have the privilege to buy food (at way over the odds) from a bunch of stalls.
In fairness to the organisers, it's a brilliant earner.
