Over the last 2 weeks I had a chance to check out both Lounge L and SPC.
They seem almost identical, though SPC might be a bit bigger and have more power points.
Both brand spanking new. About 8 hot dishes, bread, soup, cookies etc.
Draft beer and mediocre wine plus soft drinks.
Chase Sapphire Reserve recently added the digital card option, and I could use my digital PP card on my iPad.
