R. F. O'Sullivan & Son Pub

RF O’Sullivan is a classic Irish pub. Boston has a lot of those, but what sets this one apart is the burger selection. It has a ton of them, and all of them are made with enormous baseball-sized patties that are well-seasoned and perfectly cooked. Start with the house burger topped with ham and bacon if you don’t know where to start, but there’s enough variety here to find something you like.
