Glow

Glow is located inside of the Mariott (Hotel) Marina Del Rey, and has nice outdoor seating and even in the daytime the fireplace is kept burning for ambiance.

The seats are as comfortable as nice outdoor patio lounge furniture is generally.

They do have a happy hour that begins at 5:00pm on weekdays.

The parking is okay in the area, you can either do the valet with the hotel (I have no idea of the cost but based on speculation I'd venture to guess it could be expensive) or find street parking outside in the neighboring areas along Washington Blvd where there's 2 hr meters and also if you're willing to walk, maybe a few residential street parking spaces (but I doubt many without having a multitude of restrictions since this is walking distance from the beach).  

The service here was good, very accommodating.

The food was okay and on par with what's expected by hotel bar food standards in both quality and price.

I went here at a late afternoon, pre-evening weekday, so it wasn't crowded.

Great cocktails.
Great vibe.
Great service.

There were only 2 other people here when I came with a friend - score! The whole ambiance is perfect in my book. The fire in the wall, the glass fire pits, the waterfall wall, the open spaces, the gazebo structure with chairs in it. You can relax and chat with friends or look up and gaze at the sky. The service was quick and friendly. Because there were hardly any people there it was actually a very tranquil experience. I would definitely go back again!
