Lamb & Flag, Leicester Square  

This pub is pretty famous in these parts, so it ought not to need much of an introduction. It's a genuinely old, higgledy-piggledy place, with bare floorboards, plenty of dark wood panelling and little brass plaques commemorating previous punters. It's just the sort of Olde Worlde Englishe Pubbe that tourists expect to see (especially if they're here for the first time) and they love it. It might be a tourist cliché, but even for the most cynical of hardcore pubgoers, it's a jolly decent pub. It serves well-kept Young's beer and decent pub grub and, as a result of its location and fame, you'll usually find it to be pretty packed. If you can fight your way up the narrow stairs you can find a quieter spot or, if you're lucky, even a seat. If you're in the area and it looks quiet, do go in and have a pint and a nosey around. And if you like cheery, crowded, old-fashioned pubs you won't be disappointed here.
