Yakitori also refers to a type of mid to upscale Japanese pub/restaurant with a wide menu of small dishes/skewers as well as the cultural signature yakitori skewer. Thank you for the direct translation.

While you can find yakitori as a street food at night markets, both izakayas and yakitori restaurants are cozy comfortable indoor pubs/bars, with yakitori pubs generally having more service, room and tables as well as a bar, although even an izakaya a lot cleaner and more-maintained/serviced than a dive bar, and a yakitori will be a fancy hardwood upscale sort of place with a much wider menu.

Boyyyyyy do I wish it was an AYCE buffet. In both izakayas and yakitoris, you’ll pay for each order/drink and can have them freshly prepared and delivered within minutes. So maybe 2 chicken hearts and a beer, then some tsukiji a little later, breathe a bit, get some shiso-wrapped pork. It’s pretty fun and chill.

An izakaya is a different type of pub, definitely less formal, usually less service and much more cramped, often just a bar and stools. People go to izakayas after work to get a bit rowdy, and the main point is drinking, rather than the menu, and sometimes there isn’t a menu at all.

I haven’t been to a western yakitori restaurant in about 15 years now, so I’m not sure how they’re organized these days. Back then, it was just like the Japanese ones, although the one I liked was owned and operated by a Japanese immigrant yakitori masterrrr, so he probably carefully traditionally controlled his yakitori pub more than a non-native or new-to-the-scene yakitori owner might.
