Sisters' Sludge is a comfortable, neighborhood shop. Seems like most of the customers are people who've walked over. It's fairly large as the shop has two halves: coffee shop and wine bar. Lots of tables and outlets. The shop has the standard selection of coffee drinks and brews. They've got a simple kitchen and have a good assortment of baked goods. The staff, including the sisters, are warm and welcoming. Not remarkable coffee but enjoyable. Overall, a nice coffee shop that's got something for everyone although hip coffee snobs will be disappointed.
