Dark and ornate, but dive-ish in vibe, this crimson-colored spot remains one of the liveliest bars in Silver Lake thanks to its convenient locale, nicely stocked jukebox (warning: they play it loud in here) and drink selection. The somewhat crowded layout of furniture --lots of comfy couches, some booths, and a center bar with stools which can be hard to walk past-- facilitates fairly easy friend-making. Still, some may find 4100 a little claustrophobic at peak hours. Good luck getting a seat at all on weekends. Billowy fabric and Moroccan touches soften things up, as do the strong pours. The parking lot - a regular post for some of L.A.'s best food trucks - is a destination in itself.
