800 metre runway IIRC - depends what you're flying as to whether it's a challenge I guess.
The other attraction there is the Welshpool air show. The trick - I believe - is that a lot of the acts are shared with Cosford so it's a lot better than you would expect for the size of the airfield. Lots of interesting aircraft flying in, and very family friendly with bouncy castles and remote control boats.
The truth is I wouldn't fly in for the food, but there are plenty of other good reasons (and you won't starve).
