I love to eat at Brazilian churrascarias! If you don't know what kind of restaurant it is, do yourself a favor and check-it out! Anyone who likes meat with certainly fall in love with it. I also like places where you can eat miso-katsu, a breaded pork cutlet covered in (usualluy) red miso (soybean paste) sauce, that you can only find in Aichi Prefecture, like Yaba-ton.
Other than those, I don't care too much about going out just to eat.
If possible, I'd really like to be able to go to a bar or pub at least once a week though. As it is almost impossible, I try going at least every couple of weeks or so.
I usually don't like places where the ambient music or the noise caused by other people is too loud, so my favorite places are usually Japanese-style bars, or izakaya.
There are two here in Nagoya that I particularly like: Murasaki with their wonderful artesanal schwarzbier and their chicken-skin gyoza and Kadoya where you can drink a 1.2 litre mug of beer for fairly cheap while cooking yourself some juicy stakes.
(I feel like someone writing for a city tour panflet now)
