Sycamore Farm in Lowerhouse(near Rosegrove) does a cracking carvery...according to the missus who lunches out there on regular ocassions. not as cheap as some but never the less great. It is a really popular place with an excellent childrens area, we went the day after Boxing Day and the wait for a table was nearly 2hrs ( we did`nt bother) and they were lining up on the car park as we left........maybe the credit crunch hadn`t hit Burnley then........
and i`m sure if you ask them nicely they will carve the meat to match the size of your gob!!!!
