Ash Ryan Beats: Section 1 - Koto, 0:11 - 1:41 @ Aoya-mon Gate. Have a look at the view on the north side of the gate area, overlooking the moat with skyscrapers in the background.
Ash Ryan Beats: Section 5 - Piano, 3:24 - 3:56 @ 南外濠 (The Southern Moat). Right next to this rest house is an up-front view of the enormous southern moat that shouldn't be missed.
Ales: You have to try their "Premium pancakes" they're amazing. It melts in your mouth. Just know they make a batch of 30 at certain times 11am, 3pm etc. During the week there's no line. Gotta try them!
K B: Great place to relax with drinks and an amazing view if the weather is good. No entrance fee to rooftop if you have castle ticket ¥500 per glass of wine, beer, cocktail etc.
