There's a nice little Italian place at Huddersfield, but that's a bit far
Most of the best places in Leeds are on the outskirts. There's the Vic at the back of the Town Hall for decent pub food. Also Nash's for quality fish n chips. I had a meal in the Light once - can't remember where. Didn't taste too good.
