I've been to Granite Brewery a few times now. The service varies, from occasionally very slow to average to good. I like the food here, which is like classic pub grub.
Most recently I had the Drunken Mac and Cheese with bacon and jalapenos. It was a smaller serving than you'd expect, but probably a good size considering all the fattening ingredients! But maybe it could come with a side of vegetables? It tastes really good, and is the perfect amount of heat. I think the cheese could be sharper, but I just really sharp cheese. I also really like their quesadillas. The Key Lime Pie (my favourite dessert) was delicious, a good size to share between two, but probably no more than that.
I recommend going in the summer when you can sit on the back patio.
