I was suffering through some pretty mediocre pad Thai the other day, and began to reminisce about better incarnations of said dish that I've had in the past. I came to the conclusion that, even though I haven't been there in eight years, the Y Eatery is definitely my go-to example of Pad Thai amazingness.
Somehow they strike the perfect balance of everything - it's not greasy, but the noodles aren't dry either. It's spicy enough to be flavorful, but not overwhelming, and the tofu is good quality. It's super cheap, too!
Seriously, if had a private jet and a staff to do my bidding, there's a fair chance that I'd send them on a Y-Thai run now and then. If you are in Champaign, go to the Y Eatery! I'm very jealous.
