Monk's Cafe is more of a dank beer pub than any kind of cafe, but it's become a Philadelphia institution thanks to its staggering bottled beer list (there are more than 300 local and global brews to choose from). Yes, the place is dark. Yes, it's cramped. But the draft selection of Belgian suds makes Monk's a national leader in the category: owner Tom Peters was actually knighted in Belgium to honor his dedication. Drinkers can pick up a "beer bible" from the bar, which could pass for a novela under the dim electric candles scattered throughout. Pub fare flows from the kitchen, and while the burger won't disappoint and you can order grilled salmon if that's your thing, the true must-eat dish is the pot of mussels, flavored with sour beer-sautéed jalapeños, peppers, and onions.
