La Belle Pizza
1 Church Lane
Brecon
Pretty much does what it says on the tin; a pizza place. Mainly take-away, with a sporadically open restaurant above it. The restaurant often does things like pasta as well. Prices aren't cheap compared to some other small places, but it reflects the quality of the food there.
To find it, head towards St Mary's (the church in the centre of town), and wander down the lane by the back of the church. DO NOT try to drive a Landie down this street. It's a swine to get round, even in a smaller vehicle.
