An izakaya is a restaurant that serves alcoholic beverages and accompanying food. On Fridays, the next day is the weekend, so you can see the area crowded with people wearing suits.
Generally, small tables are set up, and it is common in Japan to have fun with friends, co-workers, and bosses.

Orders can be made directly to the shop staff, from single dishes of your preference. You may also request course menus, however, bear in mind that you might need to make prior reservations in some cases. There are also shops which offer all-you-can-drink plans, so it's a good idea to confirm with the shop when making your choice or when entering it. Prices range widely from relatively reasonable shops to expensive shops, depending on the kinds of alcohol and food as well as location. On entering and ordering some drink, you may be brought a small dish of appetizer even though you haven't ordered it, and will be charged the price later. This is called otooshi or tsukidashi and is served to fill the gap until the customer's order is served, acting as a kind of service charge. *Please be aware that this kind of system exists.

Izakayas offer a comprehensive range of typical Japanese foods such as rice balls, kamameshi, sushi, sashimi, udon noodles, ramen, okonomiyaki, fried chicken, croquettes, and curry.

And there are all sorts of alcoholic beverages, including beer, sake, shochu, whiskey, and wine.
In addition, we have a delicious sweets menu after the meal.
There may not be many restaurants overseas that have a full lineup of dishes like Japanese izakayas.

This is a system where you can order as much as you like from the all-you-can-drink drink menu for a set time. Basically, after finishing one drink, order the next drink. Soft drinks and non-alcoholic drinks are also available for those who don't like alcohol. When the time limit is approaching, many shops come to ask for the last order.
