I have been presented with the amazing opportunity to live in Tokyo for a short period of time due to a work project my girlfriend was given. Specifically, we will be living in Shinjuku. I have traveled to Japan once before on vacation and had amazing experiences at Mizutani and Sushi Dai, as well as a number of other non-sushi restaurants. Unfortunately, I have recently returned back to school and am therefore living the life of a starving student. I am looking for an affordable sushi spot in Tokyo (the closer to Shinjuku the better) that I will be able to frequent during my stay in Japan. Although I will probably splurge on a nice sushi meal or two (something along the lines of Sushi Saito), I was wondering if anyone knew of any solid lunch spots (or dinner if not too much more expensive) in the $20-30 range as opposed to $100-$300. Ideally, I plan on eating sushi multiple times a week and cannot afford much more than that. Obviously, I'm not expecting Mizutani quality, but I would obviously like the best bang for my buck because my standards are quite high (although I realize I will have to lower them now that I'm a student again). Any recommendations would be greatly appreciated! Thanks in advance!
P.S. Any other good cheap eats suggestions are also welcome (i.e. ramen, soba, udon, tonkatsu, yakitori, izakaya).
