The Perch is a trendy, hipster rooftop bar. If you're looking to get a nice view of the DTLA buildings then this is the place to go.
I came here on a Saturday night around 10pm for a friend's birthday celebration. Make sure not to miss the building as there is a tiny sign that says "Perch" There was no cover charge to get in (unlike The Standard). There was a small line to get to the rooftop, but it only took 5 mins. It was crowded inside the restaurant but the rooftop was spacious. There are limited seats with bonfire pits (so get there early or have someone grab the seats quick)
The drinks are at a reasonable price. $6-7 for bottled beers and $10-15 for mixed drinks. The staff are friendly, but don't try to sneak up to the rooftop because you will get kicked out.
Parking is either valet or you find your own spot. There is a lot on the corner that charged $15. I recommend parking at Perishing Square for $7!
