Glitch Coffee is hands-down my favorite coffee shop in Japan and one of the best, if not the best, I've been to in the world. I have to go here every time I travel to Tokyo.
Nestled in the middle of a business district in Jimbocho, Kanda, Tokyo, Glitch is in an absolutely inconvenient location, but I'd say it's absolutely worth it for coffee enthusiasts with time to spare to go to.
Their coffee options like espresso or milk drinks like lattes and flat whites are all great options. The real reason to come here, though, would be their pourover bar. At any given time they will have 6-8 coffee bean options at the front of the shop that you can choose from to get a pourover made. They have always made interesting-tasting coffees for me with these beans.
Aside from the location, the thing I can see faulting them for is price. Glitch is quite expensive - their espresso and milk drinks aren't too out of line with any other specialty coffee shop in Tokyo, but their pourovers cost anywhere from 600-2400 yen, and their coffee beans, which are also fantastic, cost 1800-5000 yen for 100-150 grams.
So to coffee enthusiasts, I'd say it's a five star shop, just be prepared for some higher than average prices. For everyone else, I would probably say don't go out of your way - there's really nothing else around so Glitch would have to be your reason for coming to this area.
