Nothing too special. Yoshi's offers quickie fast food Japanese food at reasonable prices. The happy hour deal is great: $2.77 for a teriyaki bowl with rice (Every day from 3-5 PM). It's a very basic bowl with white rice, chicken breast and teriyaki sauce. It was made in a short amount of time and we were out in no time. I did notice that they have a Coca Cola freestyle machine so you can have a custom beverage with your meal here.
The interior is a bit dingy and faded, and the atmosphere isn't the most welcoming but if you want a cheap meal this is a good option if you're in the area.
